Step 1 of 3

Problem 2E

Explain how to evaluate .

Answer;

Step-1;

The given integral is $\int\limits_{a}^{\infty{}}$ f(x)dx.

Now , we have to evaluate $\int\limits_{a}^{\infty{}}$ f(x)dx.

We , know the formula $\int\limits_{\ }^{\ }{x}^{n}$ dx = $\frac{{x}^{n+1}}{n+1}$ +C , C is constant ………..(1)

Therefore , $\int\limits_{a}^{\infty{}}\ f(x)$ dx = ${(\frac{(f(x){)}^{2}}{2}{)}^{\infty{}}}_{a}^{\ }$ +C , since from (1).

= $(\frac{1}{2}\ (f(x){)}^{2}$ ${{)}^{\infty{}}}_{a}^{\ }$ +C.

= $\frac{1}{2}$ ( $\ (f(\infty{}){)}^{2}$ -
