If f(x) = 6 sin (2x)sin-¹(x),

Find f"(x), where f(x) = tan-(sin x2019)

A student takes the derivative of the function h(x) = (x² + sin (x) )(1 − cos (x) ) as follows: h(x) = (2x + cos(x)) sin(x) Is this correct or not? Explain what the student did, and if not correct, write down the correct derivative.
