Hi out there!

I'm a student working on a test with Mathematica...and I've got
massive problems with this task here:

http://home.t-online.de/home/harrytasker/Task.nb

If it's not working, here's a scan of it

(Sorry it's in german..anyhow, it is obviously a system of equations.
I just have to plot the solution of y3(t) in the limits of 0<=w t<=4
Pi).

But how do I do it?
It shouldn't be that much work...but I don't get the idea HOW.
I tried with LinearSolve...but out comes a (very complicated) result,
which I'm not able to plot somehow.
Also, there's this Y0-thing..nothing is specified about this, should I
just take it as a constant (because Plot requests a numerical value!).

So, you see, I'm rather confused...please help me!

THANKS A LOT IN ADVANCE!

Bye 
Detlef Mueller

P.S.:I'm using Mathematica 3.0 on PC...if it's important.
