Question

What is the derivative of `sin(sin(x))`?

Answer 1

`d/dxsin(sinx)=cos(sinx)*cosx`

Explanation:

The rule says that the derivative of the sine of a function is the cosine of the function multiplied by the derivative of the function,

`therefore d/dxsinu(x)=cosu(x).(du)/dx`,

and so the result follows.
