Recently My friend gave me a question about trigo

Homework Statement



How do I Solve This?
Tan(A) + tan(B) + tan(C)

On My Own Thought
Maybe I Think That The Question Is Quite Incomplete




2. The attempt at a solution

Any Idea To Start The Calculation?

Tan(A) + tan(B) + tan(C)
is not an equation, so has no "solution".

Perhaps the question was something like this?
Prove that if A, B and C are the 3 angles in a triangle,
[itex]\tan A + \tan B + \tan C = (\tan A)(\tan B)(\tan C)[/itex]

If your hunch is correct, :smile: then I'm sure there will be plenty of solutions to be found by a google search.
