Traveling Wave

  1. Nov 23, 2008 #1
    1. The problem statement, all variables and given/known data
    The displacement (in meters) of a wave is y = 0.37 sin((pi)t - 3.88(pi)x), where t is in seconds and X is in meters.

    What is the displacement y when t = 34.4 s and x = 6.7 m?

    2. Relevant equations
    y = 0.37 sin(t - 3.88x)

    3. The attempt at a solution
    y = 0.37 sin((pi)34.4-3.88(pi)6.7)
    y = .16452 meters

    What am I missing here? All I should have to do is plug the t and x values into the given equation right? For some reason I'm getting it wrong.

    Hi JJones_86,

    You need to set your calculator to radians.
