Some help with this geometry problem...

Revision en1, by fastnoise, 2016-07-11 19:19:16

A few days ago I read this problem, it seem like a easy geometry problem about optimization over the angles, so I used ternary search to rotate the point about the origin, like the picture show, but I got WA, so, any idea about what's my error? ****

Rotating the point

Thank you very much.
