Explanation:

Assume base differentiation knowledge: Sin(x) = Cos(x), Cos(x) = -Sin(x)The question combines the chain and product rule. To begin, start by splitting the equation: Sin(2x)Cos(x) = Sin(2x) x Cos(x)The product rule formula is dy/dx = u(dv/dx) + v(du/dx), where in this case u = Sin(2x) and v = Cos
