Horizontal Shift - Phase Shifthorizontal shift and phase shift:If the horizontal shift is positive, the shifting moves to the right. If the horizontal shift is negative, the shifting moves to the left. From the sinusoidal equation,y = A sin (B(x-C)) + D the horizontal shift is obtained by determining the change being made to the x value. The horizontal shift is … [Read more...] about Horizontal Shift – Phase Shift
