Find the derivative of(i) `(x^5-cosx)/(sinx)` (ii) `(x+cosx)/(tanx)`

Explanation

To find the derivatives of the given functions using the quotient rule, we will follow these steps:

### Part (i): Derivative of \((x^5 - \cos x) / \sin x\)

1. **Identify \(u\) and \(v\)**:
- Let \(u = x^5 - \cos x\)
- Let \(v = \sin x\)
