Can someone help me with this "easy" wave question?(adsbygoogle = window.adsbygoogle || []).push({});

I am given a sine wave. The snapshot shows a point of zero displacement at x=0. In terms of period of T of the wave, when will a) peak and b) the next point of zero displacement reach x=0?

the answer for a) is 3/4T and for b) is 1/2T

can someone please explain?
