The graph of y = A sin (Bx + C) is obtained by horizontally shifting the graph of y = A sin Bx, where

1) Amplitude = |A|,

the maximum of y is A, if A > 0 and -(-A) if A < 0

The minimum of y is -A if A > 0 and A if A < 0

2) Period = (2pi)/B

3)Phase shift = C/B So that the starting point of the cycle is shifted from x = 0 to x = C/B. If C/B > 0 the shift is to the right. If C/B < 0 the shift is to the left.
