Arrived at this equation after I'm halfway done with a problem and can't figure out a way to isolate theta.
Maybe you messed up somewhere earlier. Any chance that you might post the original equation?

It's just the usual parameterization of a particle on an earth trajectory (no drag forces or anything, just the gravitational potential field).
x = vcos(theta)t
y = vsin(theta)t - .5at^2
None.

Yeah I'm not a big fan of Westernhagen either, Fanta vier much better! But they didn't drop the lyrics that fit the situation. Farty: Ich bin wieder hier; nobody: in meinem Revier; Me: war nie wirklich weg
