Question
Without a calculator or computer, match the formulas with the graphs.(FIGURE CANT COPY)(a) $y=2 \cos (t-\pi / 2)$(b) $y=2 \cos t$(c) $y=2 \cos (t+\pi / 2)$
Step 1
The function $y=\cos t$ starts at the point (0,1) and is symmetrical with respect to the y-axis. The amplitude of the function is 1, which is the maximum value of the function. Show more…
