Re: solution of trianglehi mukesh, There's no right angle to get tanA easily so I used the sine and cosine rules: and Put these together to get tanA and simplify. work on this expression for tanA, making use of the following: After much simplification you can get this equal to 2tanB, from which the required result follows. It's a tough one so expect it to take 2 or 3 pages. If you get stuck post back where you've got to, and I'll compare your answer with mine.

Re: solution of triangleWell, I have a solution that takes 2 or 3 lines to write up, but requires quite a bit of inspection. The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #5 20130707 01:44:24
Re: solution of triangleI do not have an exact definition. Roughly, it means that some times you will think of it, sometimes you won't, and it mostly depends on luck, not unlike many other geometry problems.

Re: solution of triangleThe thing I dislike about those kinds of ideas are that they can be tough to get. It does come down to luck and experience a lot.
