Hi m_bayuomi;

Welcome to the forum. What did you get from the geometry lesson?

**In mathematics, you don't understand things. You just get used to them.I have the result, but I do not yet know how to get it.All physicists, and a good many quite respectable mathematicians are contemptuous about proof.**
