Step 7: Use phase shift and b to determine c. (phase shift = -c/b) Show your formula and work for credit.
The formula for phase shift is given by:
phase shift = -c/b
Given that the phase shift is 30 degrees and b = 2, we can plug in these values into the formula and solve for c:
30 = -c/2
30 * 2 = -c
60 = -c
c = -60
Therefore, c = -60.
