A. Choose a composite trigonometric function of the formh(x) = g(f(x))where the function g is one of the trigonometric functions and f is any function more complicated thany=x.

Note: An example of an appropriate function h would beh(x) = sin(3x - 4). However, you must pick a function other than this example for this task.

1. Show the step-by-step computation of the correct derivative ofh(x) using the chain rule.

2. Using the functionhyou constructed for part A, find the instantaneous rate of change atx= /3.
