Evaluate the following integrals :
`(i) int sin^(4)xcos^(2)xdx` `(ii) intsec^((4)/(9))x cosec^((14)/(9))xdx`

Explanation

To evaluate the given integrals, we will solve them step by step.

### (i) Evaluate the integral \( \int \sin^4 x \cos^2 x \, dx \)

1. **Rewrite the integral**:
\[ I = \int \sin^4 x \cos^2 x \, dx \]
