Hi If you lokking for the basic Idea of Product Rule then it is as follows:
The product of two differentiable functions, f and g, is itself differentiable. Moreover,
the derivative of fg is the first function times the derivative of the second,
plus the second function times the derivative of the first.
d/dx[f(x)g(x)] = f(x)g'(x) + g(x)f'(x)
