**MathMate**, Thursday, December 17, 2009 at 6:29pmMost of these questions can be answered by the definition of the general trigonometric functions:

y = a sin A(x-φ)

a is the amplitude

2π/A = period

φ = phase shift.

If you can transform the trigonometric functions into the above form and evaluate the values of a, A, and φ, the answers would become apparent.
