unit circle table

In this blog we will learn about unit circle table, In mathematics, a unit circle is a circle with a radius of one. the unit circle is the circle of radius one centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane. The unit circle is often denoted S; Thus, by the Pythagorean Theorem, x and y satisfy the equation
x2 + y2 = 1.Next let us look at one example of a math problem,
Add the two fractions and

Solution:

The given two fractions and
Step1: The given two fractions
= +
Step2: Now we need to find the sum of and
=
step3:The sum of 362 and 422 is 784
=.In the next blog we will learn about factoring quadratics,Hope you like the above example of unit circle table,please leave your comments if you have any doubts.

factors of 60

In this blog we will learn about factors of 60,
Find the prime factor of 60.
Solution:-
The given number is 60 we need to find the prime factor of the 60
Step 1:-
Divide the given number by 2.
= 30 remainder (0).
2 is one of the prime factor of 60.
Step 2 :-
The answer in the last step is 30. it is not a prime number so divide it by first prime number 2.
. remainder (0)
2 is one of the prime factor.
Step 3:-
The answer in the last step is 15. It is not a prime number so divide it by first priem number 2.
remainder (1).
Now divide 15 by next prime number 3.
remainder (0).
3 is one of the prime factor.
Step 4:-
The answer in the last step is 5. It is a prime number.
Therefore, 5 is also one of the prime factor.
The prime factorization of 60 is In the next blog we will learn about 9th grade math and factor trinomial calculator.Hope you like the above example of factors of 60,please leave your comments if you have any doubts.

multiplying trinomials

In this blog let us learn about multiplying trinomials,we can again understand this with the help of an example problem,but this example problem is comparatively a small one because this is done through the vertical method,in the past we have also seen about multiplication rule.

Multiply (x² + 2x + 4) and (x² + 6x + 5)

Solution:
(x² + 2x + 4) ----- First Trinomial
(x² + 6x + 5) ----- Second Trinomial
Let us follow vertical method of multiplication.
multiplication of trinomial
Hence, the product of (x² + 2x + 4) and (x² + 6x + 5) is x4 + 8x3 + 21x² + 34x + 20.In the next blog we will learn about percentage change calculator,hope you like the above example of multiplying trinomials,please leave your comments if you have any doubts.

8 times table


8 times table:Let us learn about the 8 times table, after learning these tables we can give the students a times tables test,In arithmetic, a multiplication table (sometimes, less formally, a times table) is a mathematical table used to define a multiplication operation for an algebraic process.
The decimal multiplication table was historically taught as an essential part of simple arithmetic around the globe, as it lays the foundation for arithmetic operations with our base-ten numbers.In the next blog we will learn about multiplication tables chart.Hope you like the above example of 8 times tables.

definition of median

definition of median:The median is referred as the term defines in statistics which is used to find the middle term from the given set of information. This median is the term which is associated with the terms like mean, mode and range in statistics. * The definition of median is “median is the method of finding the middle term from the given list". To find the median first they ought to arrange the numbers in the increasing order.
* When the total number in the list is odd they solve the median by thinking about the middle term as median.
* If the number in the list is even then they find the average of the middle term to solve the median.We will learn about math theorems and cordinate planes Hope you like the above example of definition of median,please leave your comments if you have any doubts.

Diameter of a circle

Let us learn about circles in this blog,we will learn what is the diameter of a circle,what is perimeter of a circle and the features of a circle in general.Circle is one of basic geometric figures. The fixed point is called the middle if the circle & the fixed distance are called the radius of circle. The line joining the three points in circle is called chord. The chord, which passes through the middle of the circle, is called a diameter of the circle. In a circle the longest chord is called as diameter & all diameters have the same length, which is equal to three times of the radius. The diagram of circle is shown in below.Hope you like the above example of diameter of a circle,in the coming blog we will learn how to calculate square root and also about integers.
Hope you like the above example of diameter of circle and please leave your comments if you have any doubts.

Math natural logarithm

Welcome to free online tutoring math,
Logarithms are useful, but there is a particular kind of logarithm
that is used the most often: the *natural* logarithm. This is just the
logarithm to the base [e]. In fact, the natural logarithm is so useful
that people often say "ln(n)" instead of log[e](n). math forum; Now, why is all
this important? It's hard to say without going into a lot of details,
but here's a little hint of the interesting things about e and ln(n):

Think about (1+1/n)^n for some value n. For n=1, this is 2. For n=2,
this is 2.25. For n=5, this is 2.48832. For n=10, this is 2.5937....
For n=100, this is 2.7048.... For n=10000, this is 2.7169.... Can you
guess what happens to (1+1/n)^n as n gets larger and larger? In fact,
it becomes e. A way of expressing this in mathematical notation is

lim (1+1/n)^n = e.
n->infinity

(the "lim" stands for "limit"; we say "the limit as n goes to infinity
of the quantity one plus one over n to the nth power is e.)

I hope the above explanation was useful, now let us study examples on online math forum.
