Differentiate w.r.t to x ,`(ax^(2)+cotx)(p+qcosx)`

Explanation

To differentiate the function \( y = (ax^2 + \cot x)(p + q \cos x) \) with respect to \( x \), 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:

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