Question 1162459: Consider the graphs of y=sin x and y=cos x. Determine 2 ways in which graph of cos function can be expressed as horizontal translation of the sin function. you can sketch these graphs. Answer by Edwin McCravy(20060) (Show Source):
The red curve is of y = cos(x), the purple curve is of y = sin(x).
If we shift the purple (sine) curve left by π/2 units, it will
coincide exactly with the red (cosine) curve.
That is to say
If we shift the purple (sine) curve right by 3π/2 units, it will also
coincide exactly with the red (cosine) curve.
That is to say
