I'm stuck trying to figure out how to solve for a derivative. Any help would be greatly appreciated.

The problem I am stuck on is: d/dx sinh(x3).I know the derivative of sin(x) is cos(x) and the derivative of x3 is 3x2, but I am getting stuck on the h part and putting it all together. Thanks again... more
