Constructing Arguments CA 1. Vinny and Alisa were arguing about how to write the equation of the following sinusoidal graph. Explain who is correct and why. Vinny: I think we should write the equation using cos. If you look at the interval from -Tt/2 to 3t/2. It is a perfect cosine cycle ST/2 Alisa: You are dumb! This is obviously a sin graph. From the interval -T to n there is a -T2 perfect sine cycle.
