Learn how to solve problems step by step online. Find the derivative using the product rule d/dx(5(cos(x)+sin(x))(cos(x)-sin(x))). Apply the product rule for differentiation: (f\cdot g)'=f'\cdot g+f\cdot g'. The derivative of the constant function (5) is equal to zero. Any expression multiplied by 0 is equal to 0. x+0=x, where x is any expression.
