I know that curvature is [itex]\kappa=|d\phi/ds|[/itex], where [itex]\phi[/itex] is the angle between the curve's tangent vector and the horizontal, and s is the arc length.

I also get that the way to do this is to make it [itex]\kappa=|d\phi/dt/(ds/dt)|[/itex], I get lost, however, in actually finding a good equation for [itex]\phi[/itex].

Does anyone have any tips, resources, or advice?
