Starting Laplace's equation

  1. Dec 8, 2011 #1
    The question involved solving the "T" on a plate sized from (0,0) to (1,2). Any ways, I will spare you of the details and get to the line in the solution I was confused with:

    Bottom: T(x,0) = 1-x = Bn (sinh 2n∏) (sin n∏x) = bn (sin n∏x)

    The next line confused me: bn = 2 01 (1-x) sin n∏x dx

    How did they arrive at that equation to solve for bn? thanks

    (forgot to read the stickies, move this post if you wish, thanks)

    Hi zheng89120! :smile:

    That looks like the Fourier series instead of the Laplace transform.

    Btw, this looks like homework/coursework.
    Is it?
    If so, you should post in the homework section.
