Module 1.7: Graphics vs. Equations

   Q1.   The wave shown in red is given by y = 5cos4 t.   Which equation applies to the green wave? 
                       y = 5cos(4 t-/4)
                       y = 5cos(4 t+/4)
                       y = -5cos(4 t-/4)
                       y = 5sin4 t

   Q2.   The wave shown in red is given by y= 5cos4 t.   Which equation applies to the blue wave?
                       y = 5cos(4 t-/4)
                       y = 5cos(4 t+/4)
                       y = -5cos(4 t-/4)
                       y = 5sin4 t
