The simultaneous applications of signals x (t) and y (t) to the horizontal and vertical plates respectively, of an oscilloscope, produce a vertical figure of 8 displays. If P and Q are constants and x(t) = P sin (4t + 30), then y(t) is equal to _____
1.Q sin (4t -30)
2.Q sin (2t +15)
3.Q sin (8t +60)
4.Q sin (4t +30)
