"PHASE SHIFT" CHANGES IN Y = SIN (X)
(Susan M. Hewitt)
PHASE SHIFT is the number, S , in the formula below:
y = a sin (b ( x - s )) + v
Phase Shift tells us the how the graph of y = sin(x) has been shifted.
Right if s>0 and left if s<0.
In this example, s = 2 radians.
So, the the new curve has been shifted 2 to the right of y = sin(x).
In radians, it is (2 pi / 2) or ( pi ) radians.
