Find the derivative of the following functions (it is to be understand that a,b,c,d,p,q,r and s are fixed non-zero constants ):
`co sec x cot x`

Explanation

To find the derivative of the function \( y = \csc x \cdot \cot x \), we will use the product rule of differentiation. The product rule states that if you have two functions \( u \) and \( v \), then the derivative of their product is given by:

\[ \frac{d}{dx}(uv) = u'v + uv' \]

### Step 1: Identify the functions
Let:
