2) Sketch the graph of y = Vztan(2x). a) First, find its period and amplitude. b) Second, find the interval in which the graph completes one cycle. c) Third, divide the interval into 4 equal parts to find the 5 key points for graphing. X -2 *1 0 1 v l l 0 l l cl) Use the 5 key points to graph the function. 3) Sketch the graph of y = 4csc(2x). Hint: Graph y = 4sin(2x) first. a) First, find its period and amplitude. b) Second, find the interval in which the graph completes one cycle. (2) Third divide the interval into 4 equal parts to find the 5 key points for graphing. d) Use the 5 key points to graph the function
