Find the no differential coefficient of
x² cos a​

Answer 1

Answer:

The derivative of cos(2x) is -2sin(2x). The process of finding this derivative uses the chain rule. We can use integrals to check our work when finding derivatives. If D(x) is the derivative of f(x), then the integral of D(x) is f(x) + C, where C is a constant.
