Using your calculator look at the graph of the functions f(x)=sin x and f(x)=sin(4x). Notice the graph repeats 4 times in the length of time it took sin x to complete one period. So the period of f(x)=sin(4x) is or . Look back at 9c. The 2 shifted the graph 2 units to the left.

Making use of sine and cosine functions. Your calculator handles sin and cos functions just like the tan function. Which function to use depends on which two side-length measurements you know (or want to find out), and where those sides are compared to the angle whose size you know (or want to find out).
