Review Exam 2 1. Be able to sketch the graphs of y = sin(x) and y = cos(x) from memory and label the key points on the graph. Use the graphs to find values of the functions. (see additional problem 1 below.) NO CALCULATOR 2. For y = k + Asin(Bx + C) and y = k + Acos(Bx + C) be able to find the period, amplitude, vertical shift, and phase shift algebraically and graphically. 3. Given a graph of an equation in the form y = k + Asin(Bx + C) or y = k + Acos(Bx + C) be able to determine the equation. (That is find k, A, B, C) 4. Be able to sketch graphs with your calculator. 5. Given information about the max, min, period be able to find an equation to match the info. 6. Be able to sketch/recognize graphs of tan, cot, sec, csc.

From the graphs of y = sin(x) and y = cos(x) find the value of each of the following. A) sin( /2) B) sin( ) C) cos(0) D) cos( /2) E) cos( ) 2. Suppose that the height above ground for a person riding a ferris wheel is given by the equation h = 20cos( t 5 ) + 25 where t is time in seconds since the start of the ride. A) How high is the highest point on the ride? How high is the lowest point ? B) How long does it take for the ferris wheel to complete one revolution? C) What is the height 3 seconds after the ride begins? (round to the nearest foot)...
