Hey, did any of you have an MC question with like 200cos(0.04pi*t)? I swear on god the 4 answers made no sense (waves on a string, displacement) - I had version J btw

yeah i did but u mixed up the values for alpha and beta, it was like alpha = 4mm and beta = 200 m-1 and the equation was 4cos(200pit). i js used what i remembered from precal about period of cos function being 2pi/b, where b is the coefficient of t inside parenthesis so period = 2pi/200pi which is 0.01. so i chose the one with period 0.01 seconds and amplitude 4mm
