Does anybody know how to solve this differential equation:
[tex] \frac{d^2 \theta}{dt^2}A\sin(\theta) \frac{B^2 \cos(\theta)}{ \sin^3(\theta) }=0 [/tex] This is an equation that i get from the brachistochronic motion on the surface of a sphere.

Hi TimJ! Welcome to PF!
(have a theta: θ and an omega: ω ) so d(ω^{2})/dθ = 2Asinθ + 2Bcotθcosec^{2}θ
