Part B dy Since y(t) can be expressed as a product of two functions, y(t) = f(t) · g(t) where f(t) = you at and g(t) = cos(wt), we can use the product rule of differentiation to evaluate find the derivative with respect to t of f(t) = you¯at. However, to do this we need to find the derivatives of f(t) and g(t). Use the chain rule of differentiation to dt ▸ View Available Hint(s) Уо α -at df dt 0 (since yo is a constant) -ayoe Yoe-at -at -atyoe-at
