Hello all
I am trying to use DSolve to solve a ode with discontinuity in it (wave
equation with a viscous damper injected at a location d)
This is what i am using
DSolve[{y''[x]-lamda^2*y[x]==DiracDelta[x-d]*y[x],y[0]==0,y[L]==
=0},y[x],x]
the problem I am facing is that
y[x] on the right hand side (next the delta function) varies w.r.t to
the location
y[x]==y[x]&& 0<=x<=d
y[x]==y[L-x]&&d<=x<=L
I can solve the above equation without the y[x] coupled to the delta
function
Please advise and thanks in advance,
Pratik Desai
ps: This is my third attempt at posting my query, I hope this time it
makes it to the list :)
