Wave equation

  1. Feb 20, 2014 #1
    Hello guys,
    I would like to ask some questions regarding my coursework, which is about 2nd ODE and multivariable calculus.
    Since we have the one-dimensional wave equation and values for the string stretched between x=0 and L=2: 0≤x≤L, t≥0
    The string is fixed at both ends so we have :
    u(_,t)=u(_,t) = 0 , t≥0
    now we assume string is raised a distance μ at x=b and released from rest at t=0, Zero velocity implies: ∂u/∂t (_,_)=0 . 0≤x≤L

    thanks beforehand!

    Welcome to PF;
    That's what we are here for. However, you didn't ask any questions. Instead, you appear to have presented a situation.

    ... what are the underscore characters supposed to represent in the above?

    Are these blanks in the question you are supplied with?

    And the initial position is u(x,0) = ? Or is that what you are asking?

    I'm concerned that this is a homework question of the "fill in the blanks" style.
    If that is the case then LCKurtz may just have done your homework for you - well done!
    You should be able to figure the initial function though.

    Perhaps you are correct, although I wouldn't expect something that trivial here.
