Derivaton of Antinodes

  1. Mar 5, 2009 #1
    The eq. of standing waves is y(x,t) = 2Asin(kx)cos(wt). Derive the eq. for postion of antinodes.

    I know I can figure it out by assuming sin(kx) = 1, but I can't figure out how to get from there to final eq.

    Any help? Thanks.

    Welcome to PF :smile:

    Can you solve this related equation:
    sin θ = 1​
    That will help with finding the solution to sin(kx)=1.
