Question

what is the derivative of Cox sin x​

Answer 1

Answer:

The derivative of Sinx cosx is cos2x.

Answer 2

Answer:

The product rule can be used to differentiate any function of the form

f(x)=g(x)h(x). It states that f′(x)=g′(x)h(x)+g(x)h′(x)

The derivative of sinx is cosx and the derivative of cosx is −sinx

f′(x)=cosx(cosx)+sinx(−sinx)

f′(x)=cos2x−sin2x

Use the identity cos2x=cos2x−sin2x

f′(x)=cos2x
