Homework Help: Graphing a d.e. w/ a discountinous forcing function

  1. Dec 1, 2005 #1
    hey all
    i have the following d.e.
    y''+y=f(t); y(0)=0, y'(0)=1;
    f(t)={ 1 , 0<=t < pi/2
    { 0, pi/2 <=t < infinity
    so i solved the d.e.
    and i got
    Y(t) = 1+sin-cost-U_pi/2[1-sint]
    i did all the work, i just don't know how to go about graphing the funciton..
    any help would be appreciated.

    I'm having great difficulty trying to figure out what you mean in your expression for Y(t). :frown:
