Given the below equation of a sinusoidal wave, find the maximum transverse speed of a point on the string. y(x,t) = .00325m * sin(70x -3t) I am brand new to waves and trying to figure out what this question exactly means. The way I see it is that it might be at a max speed when 70x-3t = 1 because then the equation would just equal the amplitude. x is related to distance and t is related to time. the function is a position function I think so taking the derivative should give its velocity function. dy/dt = v = .2275m cos(70x-3t) Now my thinking has changed. Would velocity be at its max when 70x-3t = 0 since cos(0) = 1? 70x = 3t t = 70x/3 or x = 3t/70 Ha, I have no idea where I'm going with this. I'm just studying ahead.
