Find derivative of the following functions (it is to be understood that a, b, c, d, p, q, r and s are fixed non-zero constants and m and n are integers): `(a x^2+sinx)(p+qcosx)`

Explanation

Let `f(x)=(a x^2+sinx)(p+qcosx)`


Let `u=(a x^2+sinx), v=(p+qcosx)`


using product rule


`f'(x)=u'v+v'u`
