Help! Coupled differential for double pendulum system.

Otherworlder · #1 Aug 30, 2006, 09:10 AM

I have two second order differential equations that describes a double pendulum system:

y''[x] = g(y[w]-y[x])/a
y''[w] = 2g(y[x]-y[w])/b

I tried in mathematica

DSolve[{y''[x] == g(y[w]-y[x])/a,y''[w] == 2g(y[x]-y[w])/b},{y[x],y[w]},x,w]

but it didn't work. Can Mathematica actually solve that? I looked through the equation pages here and didn't find it either. Anybody has any ideas? I greatly appreciate the help
