"There are two sine waves having a phase difference of 20 degrees. After one reaches its maximum value, how much time will pass until the other reaches its maximum, assuming a frequency of 60 Hz."(adsbygoogle = window.adsbygoogle || []).push({});

Should I go about this by assuming...

sin(120pi*t) = sin(120pi(t + x) - 20)

Any hints appreciated
