Laplace little differet one

  1. Apr 22, 2004 #1
    This one has me stumped

    Find the Laplace Transform of the unknown solution function for the following initial value problem:

    y'' + 4y' - 5y = te^t, y(0)=1, y'(0)= 0

    (Do Not actually find the function, only its transform. Then, without carrying out the steps, indiacate briefly how you would proceed to find the unknown solution function.)

    As with your other question, Laplace transforms are linear thus you can do each elemnt individually. What have you done thus far?

    Also, [itex]L \{ y^{(n)} \} [/itex]

    where n is the derivative is


    PS. click on the equation to see how to use LaTex extensions. A little popup box should appear with a "click to read LaTex guide" at the bottom.

    Good luck.
