Greetings dear friends. In this article, we will share with you what is the integrate of arcsin(x).



arcsin integrate






Integral of arcsin(x) = $x.arcsin(x)+\sqrt{1-x^2}+C$

>>> $arcsin(x)=sin^{-1}x$

>>> $\int arcsin(x).dx=\int sin^{-1}x.dx$

>>> $\int arcsin(x).dx=x.arcsin(x)+\sqrt{1-x^2}+C$

Hello everyone. This lesson we will tell the integrate of $\int \frac{x}{x-1}dx$.


What is the integral of x/x-1?


integral of x/x-1





First we separate the expression.

So;

$\frac{x}{x-1}=1+\frac{1}{x-1}$

So our answer;

$\int \frac{x}{x-1}dx=\int 1 dx+ \int \frac{1}{x-1}dx=x+ln|x-1|+C$

$\sqrt{1+\sqrt{1+\sqrt{x}}}$ derivative | What is the derivative of $\frac{d}{dx}\sqrt{1+\sqrt{1+\sqrt{x}}}$?

Hello everyone. This lesson we will tell the derivative of $\sqrt{1+\sqrt{1+\sqrt{x}}}$.


What is the derivative of $\sqrt{1+\sqrt{1+\sqrt{x}}}$?





Compute the derivative of $\sqrt{1+\sqrt{1+\sqrt{x}}}$.


Here we have a more complicated chain of compositions, so we use the chain rule twice. At the outermost “layer” we have the function $g(x)=1+\sqrt{1+\sqrt{x}}$ plugged into $f(x)=\sqrt{x}$, so applying the chain rule once gives


$\frac{d}{dx}\sqrt{1+\sqrt{1+\sqrt{x}}}=\frac{1}{2}(1+\sqrt{1+\sqrt{x}})^{\frac{-1}{2}}.\frac{d}{dx}(1+\sqrt{1+\sqrt{x}})$

Not we need the derivative of $\sqrt{1+\sqrt{x}}$. Using the chain rule again:

$\frac{d}{dx}\sqrt{1+\sqrt{x}}=\frac{1}{2}(1+\sqrt{x})^{\frac{-1}{2}}.\frac{1}{2}x^{\frac{-1}{2}}$

So the original derivative is

$\frac{d}{dx}\sqrt{1+\sqrt{1+\sqrt{x}}}=\frac{1}{2}(1+\sqrt{1+\sqrt{x}})^{\frac{-1}{2}}.\frac{1}{2}(1+\sqrt{x})^{\frac{-1}{2}}.\frac{1}{2}x^{\frac{-1}{2}}$

=$\frac{1}{8\sqrt{x}.\sqrt{1+\sqrt{x}}.\sqrt{1+\sqrt{1+\sqrt{x}}}}$

Using the chain rule, the power rule, and the product rule, it is possible to avıid using the quotient rule entirely.

Product Rule for Derivative | How to take the multiplication derivative?

Hello everyone. This lesson we will tell the product rule for derivative.


Product Rule for Derivative



product rule of derivative




Let f(x) and g(x) be two functions. Then the derivate of the product

$(f(x).g(x))'=f'(x)g(x)+f(x)g'(x)$

We must follow this rule religiously and not succumb to the temptation of writing $(f(x)g(x))'=f'(x)g'(x)$ ; a faulty statement.


Example:

$(x^3.e^x)'=(x^3)'.e^x+x^3(e^x)'$

=$3x^2e^x+x^3e^x$

Quotient Rule for Derivative | How to take the derivative of the quotient?

Hello everyone. This lesson we will tell the quotient rule for derivative.

Quotient Rule for Derivative



quotient rule derivative


Let ݂f(x) and ݃g(x) be two functions. Then the derivative of the quotient:

$(\frac{f(x)}{g(x)})'=\frac{f'(x).g(x)-f(x).g'(x)}{[g(x)]^2}$

This is how the derivative of the quotient is taken. Now let's reinforce the issue with an example.


Example:

What is the derivative of $(\frac{x^3}{e^x})'$

$(\frac{x^3}{e^x})'=\frac{(x^3)'.e^x-x^3.(e^x)'}{(e^x)^2}$

$=\frac{3x^2e^x-x^3e^x}{(e^x)^2}$

$=\frac{x^2e^2.(3-x)}{(e^x)^2}$

$=\frac{x^2(3-x)}{e^x}$

$\int \frac{x^2+1}{x^2-1}dx=?$ | What is integral of (x^2+1)/(x^2-1)

You can reach integral of (x^2+1)/(x^2-1) answer on this page.


What is integral of $\int \frac{x^2+1}{x^2-1}dx$?


integral of (x^2+1)/(x^2-1)



Solution:

Performing polynomial long division, we have that:


$\int \frac{x^2+1}{x^2-1}dx=\int (1+\frac{2}{x^2-1})dx$

$=\int dx + \int \frac{2}{x^2-1}dx$

$=x+\int \frac{2}{x^2-1}dx$


Using partial fraction on the remaining integral, we get:


$\frac{2}{x^2-1}=\frac{A}{x-1}+\frac{B}{x+1}=\frac{A(x+1)+B(x-1)}{(x+1)(x-1)}=\frac{(A+B)x+(A-B)}{x^2-1}$


Thus, A + B = 0 and A − B = 2. Adding the two equations together yields 2.A = 2, that is, A = 1, and B = − 1. So, we have that:

$\int \frac{2}{x^2-1}dx=\int \frac{1}{x-1}dx-\int \frac{1}{x+1}dx$

Therefore,

$\int \frac{x^2+1}{x^2-1}dx=x+\int \frac{2}{x^2-1}dx$

$=x+\int \frac{1}{x-1}dx-\int \frac{1}{x+1}dx$

$=x+ln|x-1|-ln|x+1|+C$


Answer : 

$\int \frac{x^2+1}{x^2-1}dx=x+ln|x-1|-ln|x+1|+C$

What is integral of ∫sinx^5dx?



integrate of sinx^5



Evaluate $\int sin^5{x}dx$.

Rewrite the function:

$\int sin^5{x}.dx=\int sinx.sin^4x.dx=\int sinx(sin^2x)^2.dx=\int sinx(1-cos^2x)^2.dx$

Now use u=cosx, du=-sinxdx:

$\int sinx(1-cos^2x)^2.dx=\int -(1-u^2)^2du=\int -(1-2u^2+u^4)du$

=$-u+\frac{2}{3}u^3-\frac{1}{5}u^5+C$

=$-cosx+\frac{2}{3}cos^3x-\frac{1}{5}cos^5x+C$

How to find the slope of a graph? (Examples and answers)

Hello everyone, in this article, we will tell you how to find the slope of a graph and how to calculate it with examples. We wish you a good work ahead...


How to find the slope of a graph?



The slope of a line is determined by the ratio $\frac{change in y}{change in x}$ between any two points that lie on the line.


The slope is the constant rate of change of a line.


Example:

Use a graph to determine the slope of a line.

Slope of graph = -1/2



Step 1: Identify two points on the line. In this case, use (0, 2) and (2, 1).

Step 2: Calculate the vertical change from one point to the next. In this case, you must count down 1 space to move from the point (0, 2) to the point (2, 1).

Step 3: Calculate the horizontal change from one point to the next. In this case, you must count right 2 spaces to move from the point (0, 2) to the point (2, 1).

Step 4: Write the ratio showing $\frac{vertical change}{horizontal change}$ in simplest form.

In this case, the slope is represented by the ratio $\frac{-1}{2}$ , or $-\frac{1}{2}$ .

Solution: The slope is negative because the line falls from left to right.

Answer = -1/2
