[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 )

[tex]

\frac{d^2 \theta}{dt^2}-A\sin(\theta)-

\frac{B^2 \cos(\theta)}{ \sin^3(\theta) }=0

[/tex]

Try writing d

so d(ω
