Question 860120
Please help me graph at least three cycles of this function and indicate the amplitude, period, and phase shift. Give exact values. f(t)=3/2*cos(1/2*t+pi)-1
------
Construction:
It's a cos curve
amplitude is 3/2
Period is (2pi)/(1/2) = 4pi~ 13
phase shift = pi/(1/2) = 2pi to the left
vertical shift is -1
