1. A series of ocean waves have the form f(x)=10sin(38t)+12 feet, where the ocean floor is at f(x)=0 feet. What is the highest a wave reaches above the ocean floor? What is the period of the waves?

2. Find the stretching factor, period, phase shift, and vertical shift of the function given by the equation f(x)=8cot(0.2(x/7))2.
