Discussion of Problem 1874. Football Goal

Need help with prove
Posted by exwRabbits_AlMag(VNTU) 19 Dec 2012 09:22
The key for solution was realizing that the ends of the sticks was on the same distance from origin. How to prove that?
I have a function F(angleA, angleB). I took derivatives dF/angleA and dF/angleB, they must be equal to zero. Then what?
