$\"\"$

\

(a)

\

The function is $\"\"$ .

\

The function $\"\"$ can be written as $\"\"$ .

\

From the table of integrals , basic formulas : $\"\"$ .

\

Therefore the integral of $\"\"$ with respective to $\"\"$ is $\"\"$ .

\

$\"\"$

\

(b)

\

The function is $\"\"$ .

\

Let $\"\"$ , then $\"\"$ .

\

$\"\"$

\

By the Power Rule, the integral of $\"\"$ with respective to $\"\"$ is $\"\"$ .

\

$\"\"$

\

$\"\"$ .

\

Substiute back $\"\"$

\

$\"\"$ .

\

Therefore the integral of $\"\"$ with respective to $\"\"$ is $\"\"$ .

\

$\"\"$

\

(c)

\

The function is $\"\"$ .

\

Substiute $\"\"$ and $\"\"$ .

\

$\"\"$ .

\

$\"\"$

\

From the reciprocal identity : $\"\"$ .

\

$\"\"$ .

\

From the basic integration formula : $\"\"$ .

\

$\"\"$ .

\

Substiute $\"\"$ .

\

$\"\"$

\

Thus, the integral of $\"\"$ with respective to $\"\"$ is $\"\"$ .

\

Therefore, the integrals $\"\"$ and $\"\"$ can be found using the basic integration formulas.

\
