Erm, I fixed a mistake in the subscripts, but now I am not so sure there aren't bigger mistakes in the transformation equations for the double pendulum.

If we assume that the origin of the coordinate system is at the origin of the first pendulum, then wouldn't the transformation equations have to be

x_1=l_1*Sin(Theta_1) y_1=-l_1*Cos(Theta_1)

x_2=l_1*Sin(Theta_1)+l_2*Sin(Theta_2) y_2=-l_1*Cos(Theta_1)-l_2*Cos(Theta_2)

I am just sort of passing throught, so I don't really want to create an account to make these somewhat major changes.—The preceding unsigned comment was added by 216.211.78.195 (talk • contribs) .

I think you are right. I've made those changes, and I hope someone will look over them. Tom Harrison ^Talk 19:04, 25 May 2006 (UTC)
