integral of sin squared x

Let us learn about integral of sin squared x
1st convert sin-squared-x to its double-angle identity: 1/2[1-cos (2x)] & then integrate which expression by conventional process to obtain the solution:
x/2 - sin(2x)/4
The integral of sin x2 is one of the Fresnel Integrals. If F(x) = sin x is an function & the derivative of function with respect to x is f(x) = cos x , then we call the integral of f(x) with respect to x is F(x). In trigonometrically term like sin, cos, tan also can be performed in integral calculus.
i.e., ⌡cos x dx = sin x + c, where c is constant.

polynomial factor calculator

Let us learn about polynomial factor calculator

Steps to find solution the algebra factoring polynomials calculator are as follows:
* Try to arrange in the order of powers.
* Given expression will be written in standard form ax² + bx + c = 0.
* Try to find the greatest common factor
* Factor any complex variables.
* Try to Solve the terms
x2 ( x3+ 5 ) ≡ x2· x3+ x2· 5 ≡ x5+ 5x2;
x2( x + 5 ) ≡ x2· x + x2·5 ≡ x3+ 5x2;
x ( x3+ 5 ) ≡ x· x3+ x· 5 ≡ x4+ 5x;
x ( x+ 5 ) ≡ x· x+ x· 5≡ x2+ 5x;
here use the identity x ≡ x1.

define function

Let us learn about define function


Functions are what we apply to describe things we want to talk about mathematically.
A function is a bunch of ordered pairs of things with the property which the 1st members of the pairs are all different from 1 another.
Best Example for define function in math:
Suppose the given function f(x) is 8x2+5x+3. Finding the value of f (2)?
Solution: Given function f(x) = 8x2+5x+3
Find the value of f (2)
Substitute the value “x” for 2, then, f (2) = 8x4+5x2+3 =32+10+3, f (2) = 45

mensuration formulas

Let us solve problem on mensuration formulas

Write the given values in a decimal form
a) Six ones and eight- tenth
b) Twenty and six - tenth.
Solution:
a) Six ones and eight- tenth = 6 + 8/10
= 6.8
b) Twenty and six – tenth = 20 + 6/10
= 20.6
Write the following terms in decimal form.
400 + 20 + 8 + 5/10 + 8/100
Solution:
400 + 20 + 8 + 5/10 + 8/100 = 428 + 5 x 1/10 + 8 x 1/100
= 428 + 0.5 + 0.08
= 428.58

box and whisker plot maker

Let us learn about box and whisker plot maker


Box and whisker plot maker is also called as box plot or Whisker plot. box and whisker plot maker is a suitable way of graphically give a picture of groups of numerical data with the use of their 5-number summaries. Box & Whisker plots are basically applied in the display of statistical analyses of a group of numbers.
A box &whisker graph is applied to display a set of data. hence that you can easily see where most of the numbers are.

The best example, suppose you were to catch & measure: the length of 13 fish in a lake: A box & whisker plot is depend on medians. The 1st step is to rewrite the data in order, from the smallest length to largest: This must be the median middle number because there are 6 numbers on each side.

simplify radicals calculator

Let us learn about simplify radicals calculator

Simplify radicals calculator will help to calculate the simplified radical expression of entered values. Simplify radicals calculator will show the work by separating out multiples of the radicand that have integer roots. Simplify radicals calculator Will simplify radical expressions for positive integers for the radical or radicands. Decimals will be rounded down. First we need to find radicands which have whole number roots & pull those outside.
Simplify radicals calculator is able to separate as the release calculator & able to find solution of any rectangle root evens negative ones. Simplify radicals calculator is comparable to solving rational equations, extra than there is 1 other step.
Functions of simplify radicals calculator
The radical functions & standard exponents be capable of separate as the denominator & the numerator of the rational purpose are equivalent trainer & that worth would be x=1.
1. √x + 6 = 10
6 is subtract on both sides
√x + 6 -6 = 10-6
√x = 4
X^2 = 2^2
x=2
2. √x + 21 = 46
21 is subtract on both sides
√x + 21 – 21 = 46 – 21
√x = 25
X^2 = 5^2
x=5

factors of 56

Let us learn about factors of 56

A factor is a number can evenly be divided into another number. Any number that can be divided by1 & itself. Numbers which can only be divided by 1 & themselves are called prime numbers. The number 1 & the number itself are factors of the number.


Factors of 56 = 2, 4, 7, 14, 28
Divide the given number by first prime number 2.
56/2= 28 remainder is (0).
2 is one of the prime facto
28/2 = 14 remainder (0).
2 is a prime factor.
14/2=7 remainder (0).
2 is a prime factor.
So the prime factor of the number 56 is 2 * 2 * 2 * 7
