You're right, I completely messed up. My mistake was a mistake correcting a mistake. I had accidentally noticed that I wasn't supposed to take the derivative of the lagrangian with respect to the r because it was a constant, and mistakenly removed only half of it from my working out, thus the...

Hi, I've derived the equation of motion for a regular single pendulum, but do not know how to solve the differential equation. I have the following: r2θ''2=mg(cosθ-rsinθ)

Oh oops, it's meant to equal zero, I forgot

The particular equation I would like to see solve is: ##\sin\theta\frac{d}{d\theta}(\sin\theta\frac{d\Theta}{d\theta})+\Theta(l(l+1)\sin\theta-m^2)## The solution for this equation is the following associated laguerre polynomial...
