The differentiation of `cos e cx` with respect to `x`is `-c o s e cxcotxdot` i.e. `d/(dx)(cos e c)=-cos e cxcotx`

Explanation

To differentiate the function \( \csc x \) with respect to \( x \), we will use the first principle of derivatives. Let's go through the steps systematically.

### Step-by-Step Solution:

1. **Define the function**:
Let \( f(x) = \csc x \).

2. **Apply the first principle of derivatives**:
