Topics covered in math

Till date i have covered up many subjects in math. Like we had covered up fahrenheit to celsius equation the other day. We also worked on 6th grade math topics like decimals, integers and many more.

Guys i only want you to check out these post and learn from them. Its very necessary for you to understand the math concept and practice it. Without practicing it, its very tough to score good marks in school.

Guys self study is a perfect way towards success. Now you guys have got many options to choice. You have the option to choice your own online tutor for your subject. You can take his/her individual interest on the subject. I suggest you to study had and gain your goal. Nobody can teach you as much as you can learn yourself. Try this out, it works...

Parallel lines

I am back her to define parallel lines, another good and interesting concept of geometrical figures. Guys have you seen a railway track, do they meet? No they don't, therefore railway tracks are said to be parallel to each other.

Now let me give you a definition of parallel lines below.

When two lines start from two different points but they move in a same plane and never meet each other at any point, such lines are called as parallel lines. You will find that the distance between the two lines are the same, same length. There is no common point on the plane but it can be said to have equidistant between them.

Come on now you guys have to define dividend, write back to me as soon as possible.

Prime numbers 1- 1000

Let me discuss list of prime numbers from 1-1000 today, it is different right. We discussed about prime numbers from 1-100

Definition of prime number:- Prime numbers are natural numbers or a whole numbers. the numbers that cannot be factored or, writer precisely, are numbers n whose divisors are insignificant and presumption by just 1 and n. Table is characterized as the set of list. Here in this content,

The following numbers are the list of prime numbers from 1 – 1000,

2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97 101 103 107 109 113 127 131 137 139 149 151 157 163 167 173 179 181 191 193 197 199 211 223 227 229 233 239 241 251 257 263 269 271 277 281 283 293 307 311 313 317 331 337 347 349 353 359 367 373 379 383 389 397 401 409 419 421 431 433 439 443 449 457 461 463 467 479 487 491 499 503 509 521 523 541 547 557 563 569 571 577 587 593 599 601 607 613 617 619 631 641 643 647 653 659 661 673 677 683 691 701 709 719 727 733 739 743 751 757 761 769 773 787 797 809 811 821 823 827 829 839 853 857 859 863 877 881 883 887 907 911 919 929 937 941 947 953 967 971 977 983 991 997

These numbers have only two factors, 1 and itself, therefore they are called as prime numbers. Lets learn what are factors of 108 shortly.

uniform distribution(probability)

One of major type of discrete probability distributions is uniform distribution.

This is what i want to explain you today. As i worked on many probability problems till now, therefore decided to work on something related to it.

Uniform distribution:- It is a process where the probability of every outcomes are the same.

I will discuss on this in more details shortly with some examples. I had explained you what is probability using an example of a card, i will do something similar again. I am sure you will enjoy that.

Guys work on some ratio worksheets to improve in ratios. Feel free to leave your comments.

Fraction simplifier

Here today i am here to explain you fraction simplifier, look at some simple fraction problems which has been simplified below.

Problem 1:

solve simple fraction: 2/4 / 2/8

Solution:

Given 2/4 / 2/8

= 2 /8 = 8 /2 alternate second fraction up-down

= 2 /4 * 8 /2

= 2 *8 / 4 *2 = 16 /8 multiply reciprocal of second fraction and first fraction

= 16 /8 = 2 simplify the fraction

Therefore, the last simple fraction is 2 or 2/1

Many such simple example will be back shortly. Let me know what is the square root of 125 if you are aware of.

easy math problems

When i work on hard math problems i use to always think hope i get some math help. I use search of methods to get math help, but earlier we did not have the facility which is available today.

I use to request my friends to sit with me and study so that i learn with them. I used to ask my teacher to explain me again and again because i never followed her in the class. Some times my teacher use to do if for me but not all the times. I use to feel very sad for that.

Now my daughter is able to work on algebra 2 worksheets quickly and that's because of the math help we get these days. I hope this help i would have received earlier and i did not have to ask some one to help me...Thank you again to the new technology.

How to add fractions

I have some simple examples to discuss with you how to add fractions...look below for the examples......I had explained you how to do division of fractions earlier.

The below problem will help you understand the concept.

How do u add these fractions 3/4 and 2/4?

Solution:

Step 1: Check the denominator of the two fractions are same.

Here the denominators of the fraction are same.

Step 2: Add the numerator of the two fractions.

(3 + 2) / 4 = 5 /4

Step 3: Simplify is not possible.

Answer: 3 / 4 + 2 / 4 = 5 /4.

Before you start working on add fractions, understand this post which will be useful.

irregular polygon

I have come up with a grade 4 math topic called the polygon. First lets learn the definition of a polygon and then lets learn what are regular and irregular polygon as well.

Definition of polygon:- Its a closed geometrical figure with three or more straight lines that meet in pairs in same vertices. The sum of all the interior angles is 180 degree and the sum of the exterior angles are 360 degree.

Now lets go ahead with the definition of the two different types of polygon.

Definition for regular polygon:
A regular polygon is defined by the angles and the sides are equal

Definition for irregular polygon:
A irregular polygon is defined as the angles and the sides are not equal and it’s the opposite of the regular polygon’s.

maths past papers

I came across a few commonly asked questions in maths past papers which i have mentioned below. We been discussing on various math questions till date and solved them also.

Look below for the simple examples which are asked in previous papers.

Example 1:

Multiply: ( x + 9) ( x + 5 )

Solution:

( x + 9 ) ( x + 5 ) = x ( x + 5 ) + 9 ( x + 5 )

= x2 + 5x + 9x + 45

= x2 + 14x + 45


Example 2:

Calculate the perimeter of rectangle with the length and width are 12 cm and 14 cm.

Solution:

Perimeter = 2( l+ w )

= 2( 12 + 14 )

= 2 (26)

= 52 cm


Now start looking for more questions once you finish it start checking math answers..and if you have any topic that i can discuss with you..keep me informed.

Free algebra help

I am here today to solve some free algebra 2 homework help for my friends how asked for help. I will solve some simple problem which will help you understand the concept perfectly.

Lets solve algebra 2 answers below.

Solve the given math algebra 1 problem for step by step use the elimination method.

14x + 44y = 116

18x + 22y = 80

Solution:

Within a problem, we have to eliminate any one variable,

First we are going to increase (multiply) the equation 2 with 2

14x + 44y = 116

36x + 44y = 160 (subtracting)

- 22x = -44

x =2

Next we are going to alternate (Substitute) the value of x on equation 1.

14(2) + 44y = 116

28+44y=116

44y=88

Y=2

The final answer is x = 2,y = 2.

Once you work on some more similar problem get that checked by algebra 2 answers online, if you are wrong you can correct yourself. Bye....

Calculus Help

Guys this is just an advice to those friends, who are looking for Free calculus help First learn the introduction of calculus before we proceed.

Introduction of calculus:- The topics involved in calculus are functions, limits, derivatives, application of derivatives, logarithm functions, trig functions and exponential functions. The two major sub divisions of calculus are differential calculus and integral calculus. In this article we shall discuss about the introduction to calculus. The following are the examples involved in Introduction to calculus.

If you need to practice just look at sites which will help you with free calculus problems and i wanted to know is are you aware that we have free calculus tutoring these days.

1 pound in dollars

I have a simple example which will help you understand how to convert 1 pound in dollars. This will help you when you go out to shop. So understand the concept well.

We been understanding other concepts of mathematics by working simple problems of mathematics lets look at the example below.

Example:-

If you are on a visit to United States of America, but you belong to England. You have with you 350 pounds. You go to the nearby shopping mall and buy a wine. The rate of wine is 200 dollars, what is the amount left with you now.

Solution:

Formula for converting pounds to dollar

1 pound 1.51 dollars

Multiplied by 350 for both sides

350 pounds 528.5 dollars

Now you give 350 pounds to shopper.

528.5 - 200 dollars = 328.5 dollars converted into pounds.

Answer: The amount left with you is 328.5 $

Look at the example, there are a few things that you observe in this example carefully such as look at how to convert1 pound in dollars along with the formula to do so. The other things i would like you to see is the dollar sign or $ this is the symbol used for dollar. We have many more math signs you will come across every day

Greater than sign

Good morning my little friends, look at the frogs here------> What do they say?

These frogs show you the greater than sign and lesser than sign here. Do you know what are these signs? We have learn t a lot about different numbers previously now lets learn these great than or lesser than signs in detail.

These signs gives us the difference in the numbers which is an essential concept in mathematics. In mathematics the symbol for "what or which is greater than"is ">"

The example below will help you understand this concept better.

George has 10 chocolates and Jane has 7 chocolates. Write this statement by using greater than sign.

Solution:

George: Number of chocolates = 10
Jane : Number of chocolates =7

7 is a lower value. Hence the statement is written as 10 >7. This concept is useful to the higher grades as it is useful to my 5th grade math friends.

Check it out and let me know your comments on this and look how George is enjoying the chocolate below.

Trigonometry problems

Hi friends...Good morning....I am here with you guys to discuss on trigonometry problems as i promised you earlier. Some problems on trigonometry have already been discussed look into them too.

Look for an example of trigonometry problem below.

If the distance of John standing from a wall is 100 m and the angle subtended by the top of the wall with the ground is 30o, measure the height of the wall in meters?

Solution:

* AB = distance of the man from the wall = 100 m

* BC = height of the wall = h (which has to be calculated)

* The trigonometric function that uses AB and BC is tan A , where A = 30o.

So tan 30o = BC / AB = h / 100

Therefore height of the wall h = 100 tan 30o = (100) 1/√3 = 57.74 m.

Lets work on coterminal angles in our next post....Guys practice many more such problems...

Trigonometry functions

Ari thematic, algebra, geometry, trigonometry are subjects which children like it world wide, i use to like mathematics a lot when i was in school. I enjoyed it and therefore wanted to share my knowledge with you guys. I had posted one post earlier also which has introduction on trigonometry.

Today when i was thinking what to start up, trigonometry functions struck to my mind. I decided to write on it, so here i am with it.

Trigonometry functions are also called as circular functions. They are functions of the angles. They are normally used to relate the angles of the triangle to the sides of the triangle. All trignometry terms are related to trigonometric functions. The basic trigonometric functions are Sine, Cosine and tangent, cot sec, cosec functions of a triangle. With all this it make us easy to find the sides of the triangle. Now let me give you the introduction of trigonometric identities.


Brief introduction of trigonometric identities:- Trigonometric identities are basically formed as the equalities is involve trigonometric functions and they prove to be true for every single value of the occurring. An identity is a basic equation that represents true for all of the possible values of its variables. Trigonometric identities are important; they involve the sums or differences of trigonometric angles.

We will solve these problems in my next post. Wait until then. But you will have to post your comment on this first.

Some problems on Trigonometry

Do you know a fact guys, how was the measurement of heights and distance of an object were calculated in the ancient times? No idea right..i am sure you are not aware of it, even for me it was a new thing to know. Trigonometry, yes friends it was calculated with the help of trigonometry.

Look for some trigonometry worksheets and work on them, to increase your knowledge. I have a few solved problem that will help you. Introduction to trigonometry is already given to you in my previous post, check that as well. Look below for some solved trigonometry problems.

Problem No1.

Let’s assume that the distance of a person from a tower is 100 m and the angle subtended by the top of the tower with the ground is 30^o, now let’s calculate what the height of the tower in meters is? Below are the steps to solve the problem.

Steps:

1. Draw a simple diagram to represent the problem. Label it carefully and clearly mark out the quantities that are given and those which have to be calculated. Denote the unknown dimension by say h if you are calculating height or by x if you are calculating distance.
2. Identify which trigonometric function represents a ratio of the side about which information is given and the side whose dimensions we have to find out. Set up a trigonometric equation.
3. Substitute the value of the trigonometric function and solve the equation for the unknown variable.

Solution:

1. AB = distance of the man from the tower = 100 m
2. BC = height of the tower = h (to be calculated)
3. The trigonometric function that uses AB and BC is tan A, where A = 30^o.
4. So tan 30^o = BC/AB=h/100

Therefore we conclude height of the tower h= 100 tan 30^o = (100)/√3 =57.74m.

Problem No 2:-

Prove the given trig expression 1 + cot A/ 1 + tan A = 1 + cos A/ sin A + tan A

Solution:

Given

1 + cot A/ 1 + tan A = 1 + cos A/ sin A + tan A

Let us take L.H.S and we prove the R.H.S

L.H.S = 1 + cot A/ 1 + tan A

Here cot A = 1/ tan A

= 1 + (1/ tan A) / 1 + tan A

= (tan A + 1/ tan A) / 1 + tan A

= 1 + tan A/ (1 + tan A) tan A

L.H.S = cot A

R.H.S = 1 + cos A/ sin A + tan A

= 1 + cos A/ (sin A + (sin A/ cos A))

= 1 + cos A/ (sin A cos A + sin A/ cos A)

= 1 + cos A/ sin A(cos A + 1)/cos A

= (1 + cos A) cos A/ (cos A + 1) sin A

= cos A / sin A

R.H.S = cot A

Hence L.H.S = R.H.S

These problems will give you a clear idea on how to solve problems on trigonometry, but that is of no use until you don't work on it so what are you waiting for, start working on it immediately. Let me know how informative you found this post.

Introduction of Trigonometry

We have worked on Arithmetic, Algebra, Geometry. Today the topic i have selected is a very interesting concept of math called Trigonometry. First let me give you the introduction to this word Trigonometry and we would learn how to solve a problem on trigonometry. There are a lot of online help you can get to understand what is trigonometry, check these sites as they are very helpful.

Introduction of Trigonometry:- Trigonometry is derived from the greek word which means "Study of a triangle" It gives us the relation between the angles. They are used to relate the angles and the length of a angle. It is used to solve problems on geometry and astronomy. With the help of trigonometry we find the height of a building.

The ratios of two sides of a triangle are taken. There are six possible combination. Each ratio is given a special name.

In this subject Greek letters are usually used.

(i) (Alpha) (ii) b (Beta) (iii) q (Theta)

(iv) g (Gamma) (v) f (Phi) (vi) l (Lamda)

and so on to indicate the measure of an angle.

Lets solve a problem of Trigonometry.

Problem No1:- Calculate the T-ratios of angle A and angle C from the given figure.

The trig function sine, it is written sin θ. We will learn on this more in my next post. Feel free to leave your comments.
