Sketch a graph of the function h(x)=3/2sec2x by first sketching a graph of y = 3/2cos2x and then drawing the graph of y=h(x) on top of it. [Since you are drawing two graphs on the same set of axes, either use a different color to distinguish between the graphs or make one a dashed curve and the other solid.] Be sure to show work and intermediate steps to demonstrate that you did this WITHOUT a calculator or graphing program.
