Trig Problem, missing arc functions?

[Lord_Jeremy]

Hey. So I'm in the midst of rewriting my autonomous routines. I'm implementing a navigation system. One of the functions I'm writing needs to find the angle of a right triangle, given the base and height. So I wrote double dAngle = Math.atan( y / x ); Netbeans highlighted this as an error... So then I deleted .atan and reinserted . and let the autocomplete come up. To my surprise, I see no atan or arctan or arcanything in the list of available methods. What the heck? Do we seriously not have inverse trig functions in our incredibly minimalist version of Java? Not having ArrayList was bad enough, but at least I could use Vectors with a million object casts everywhere. I don't even know how I can do what I'm doing without inverse trig. Google searching yields two options: Use a third party library or write my own lookup table-using methods. Have any other teams run into this issue? What are your solutions? Bah, and I was upset I had to write my own nsign...
