Question: Two waves, y1 (t) and y2 (t), have identical amplitudes and oscillate at the same frequency, but y2 (t) leads y1 (t) by a phase

Two waves, y1 (t) and y2 (t), have identical amplitudes and oscillate at the same frequency, but y2 (t) leads y1 (t) by a phase angle of 60o. If y1 (t) = 4cos (2π x 103t) write down the expression appropriate for y2 (t) and plot both functions over the time span from 0 to 2 ms.
