Function : 64+23cos[pi/6(x-7)] and 64+23sin[pi/6(x-4)]
1) Are your cosine and sine models the same function? Explain why or why not. If so, show algebraically why these two graphs are equivalent.
2) How do the trigonometric parameters amplitude, period, and phase shift compare with the transformations such as shifts, stretches, shrinks, and reflections?
