3.1. Under the section write a script that plot two sine waves on the same plot. Create a time vector t from 0 to 27 with enough samples to get smooth lines. Plot y1 = 2sin(t) with a dotted red line On the same plot, plot y2 = sin(t) with a dashed black line. Label the x-axis Label the y-axis Give the figure a title (1) (3) (3) (1) (1) (1)
