@matrix sinus or cosinus or tangent, try each and see if answer makes sense :D
@matrix i think it's tangent or cotangent in this case, or rather arc-tangent/arc-cotangent if you need to find angle
@hj Arctan is better because I need the angle and it's easier to calculate iteratively.
@hj Arctan is bad actually, because when you calculate it with Taylor polynomial it's extremely inaccurate with x < 1.
Why must this programming homework be math? 
@matrix math is fun 
@matrix tan(???)=1.0/X
@matrix ArcTan, not CoTan, that's something else, my bad.
@SystemSock @matrix made the same mistake right now... 
@SystemSock @matrix yes, we all are unique
