Math enrich

Guys today we will discuss on enrich maths problems in simpler solving methods in maths. We have worked on many simple math problems which has worked helpful to you all.

Mathematics is the study of properties, capacity, sets, using numbers and symbols, right this is what we have learn t and the elementary maths operations are addition, subtraction, multiplication and division. Algebra, geometry, calculus are concept of mathematics.

Here below lets see a few example problems to learn math enrichment.

Example 1:

Solve for x: 15x-3 = 5x+67.

Solution:

Given expression is, 15x-3 = 5x+67.

Subtract 5x on both sides, 15x-3-5x = 67

10x-3 = 67

Then add 3 on both sides, 10x = 70

Now, divide both sides by 10,

x = 70/10

x = 7 (answer)

Are you aware of related rates problems and solutions, if no don't worry i will come back with the concept shortly.

arc length formula

Lets get back to geometry today, i have arc length formula for you guys below. I have mentioned how important geometry is for us right . Now lets look at the formula below.

The arc length for a sector of a circle is given by the arc length formula S = r.θ

Here S - represents the arc length - represents the radius of the circle

θ - represents the angle in radians made by the arc at the centre of the circle

I will come back with some examples on this concept shortly. I want you guys to look at the math past papers and find out if there are some problems related to arc length and we will work on it....

picture graph

Lets see what is picture graph today...as i have explained what is a bar graph. Interesting isn't it?? Yes it is..lets learn that below.

A Line graph picture is one of the line charts. It is simple to understand the data’s. They can compare two variables in line graph pics. On Line graph pics each variable is plotting along an axis. A graph picture has a vertical & horizontal axis.

This was the definition for picture graph above, we will see what is vertex angle in our next post. Do you guys have any topic that you want me to discuss. Feel free to post your comments.

Rules of writing numbers in words

Lets see what are the rules of writing numbers in words, look below... In mathematics the numbers are also represented in the form of words.

Rules for Writing Numbers in Words:

* The number of digits in the given numbers should be notified.
* The positions of each digit are considered.
* Finally convert the each digit into words with their respective positions.

Lets learn how we can solve by factoring shortly.

list of square roots

Let us see a few examples for the list of square root.

1. Square root of 9 is equal to 3
2. The square root of 121 is 11
3. The square root of 16 is 4
4. The square root of 25 is 5
5. The square root of 36 is 6

There are many more numbers which i will discuss again shortly.


By just practicing math every day, you will find math as super math world, believe me that...

Simplify sqare root

Good morning guys....happy to see you all again.. well friends, today i have come up with simplify square roots problem. I have observed many of you guys requesting to find the simplify square root of 40.


Simplify the square root of 40?

Solution:

The given number is 40

Square root of 40 can be expressed √40

Very smallest factors of 40 = 2 * 4 * 5

Square root of 40 = √40 = √2 * 4 * 5 we know √a * a = a

So, √2 * √4 * √5

we know √2 = 1.414 , √4 = 2 and √5 = 2.236

= 2 * 1.414 * 2.236

= 6.323

Answer: The Square root value of 40 is 6.323

We will learn how to find range in our next post until then just wait...

free trignometry help

How much do we all know about trigonometry? Some of us know the definition and some of us have just heard the word called trigonometry. Many of us look for trigonometry help online to increase our knowledge.

I ask my friends who are not aware of this technology to look for these sites and not to worry about the concept.

We been provided with trigonometry geometry answers and show us the sample problems. With the help of this online trigonometry tutoring isn't it possible for us to learn trigonometry perfectly? Well, guys answer me this and send me your views on this post. Mention your concerns and let me know you, if you want to know more on this topic.

Calculus Tutor

Guys today let me give you the introduction to calculus. Are you aware in which field we need calculus? Well calculus is used in areas like engineering and science. Don't you think when we realize that calculus is used in other fields also we must get good calculus tutor.

With the help of learning calculus, we actually build a bridge which helps us to learn mathematics along with other subjects better.

There are sites which has online calculus problems solve them and if you are not aware of these problems you can take help of free calculus tutor also.

They will help you get the best help online.

Right angle triangle

Guys back with triangle again today, what is right angle triangle? Look for the different types of triangles and try working on them.

Definition of a right angle triangle:-

A right angled triangle is a triangle which has one 90 degree (right angle) in it. The longest side of the triangle is called the hypotenuse of the triangle. This hypotenuse side is opposite to the right angle (90 degree).The other two sides are called legs.

Just look at the diagram on top and get to know what is a right angle triangle.

definition of Hexagon

Good morning my little friends.. Can you guys tell me how many sides does a hexagon have? I think we have already discussed on a similar concept earlier also, does any body remember...yes, its the definition of Heptagon.

Definition of Hexagon:- A hexagon is one of the polygon, the hexagon has six sides, six vertex and six interior angles. The sum of interior angles of a hexagon will be equal to 720 degree.

Properties of Hexagon:

The below three properties are important for hexagon. They are,

1. Amount of triangles used in hexagon

2. Amount of diagonal used in the hexagon

3. Total number of the internal angles used in the hexagon

You should be able to do your homework now without any difficulty if it is topic related to geometry.

9th Grade math help

Morning Folks!!! guys i am here with grade 9 math simple problems which will be as useful and full of information as you found my post which was for 7th grade math problems.

Problem No1:-

Adding the polynomial 3x4 – 4x2 + 5x + 3 and 4x + 7x3 – 6x2 – 1.

Solution:

Use the associative property and distributive properties we get the

(3x4 – 4x2 + 5x + 3) + (7x3 – 6x2 + 4x – 1) = 3x4 + 7x3 – 4x2 – 6x2 + 5x + 4x + 3 – 1

= 3x4 + 7x3 – (4+6)x2 + (5+4)x + 2

= 3x4 + 7x3 – 10x2 + 9x + 2.

Look at the following method which is very helpful when adding two polynomials

3x4 +0x3– 4x2 + 5x + 3

0x4 + 7x3 – 6x2 + 4x – 1

3x4 + 7x3– 10x2 + 9x + 2

Problem No2:-



Diameter of the garden is 9.8 find the area?

Solution:

Diameter, d = 9.8 m. Therefore, radius r = 9.8 /2 = 4.9 m

Area of the circle = ╥ *R*R

= 3.14*4.9*4.9

= 75.46 m2

Let me come back with you with some help to my grade 10 math friends very soon until then keep :-)...
