Homework Help: Transverse wave problem

  1. Feb 10, 2008 #1
    A transverse wave on a string is described by the following wave function.
    y = (0.100 m) sin [(x/11 + 3t)]
    • (a) Determine the transverse speed and acceleration at t = 0.150 s for the point on the string located at x = 1.60 m.
    • (b) What are the wavelength, period, and speed of propagation of this wave?
    • wrong check mark

    I know that to find the transverse speed i need to find the derivative. I need a refresher on the derivative of that sin function, because im getting the wrong answer. Once i get part A ill find out part B.
    thanks in advance :redface:

    The derivative of sin(x) is cos(x).
