3. Graph one cycle of y = -4 cos ( 2x +4) + 1 State the amplitude, frequency, period, and interval for -ne cycle.

Solve for 11-13 please?

Graph one complete cycle of y = 2 (sin x cos pi/3 +cos x sin pi/3) by first rewriting the right  side in the form sin (A + B).

One cycle of a cos function begins at x = - 3π/2 and ends at x = 3π/2 a) Determine the period of the function.  b) Determine 1/4 of the period. c) Graph the function over exactly two cycles.
