Period and Amplitude - Iona Prep

Apr 25, 2007 · Conclusion: the amplitude of y = a. cos x is D. Repeat for y = tan x, y = 4 tan x and y = ⅓ tan x. What is the amplitude of each function? E. Example: Find the amplitude and period of each function and draw one period of its graph starting at the origin. The number of degrees in the period is the ending point of the cycle and should be labeled. ................
