2tan(2tan(x)) or 2tan(x)*2tan(x)?

anonymous · Answer

guessing the former

anonymous · Answer

2tan(2tan(x))

I don't remember, sorry.  I do remember drawing a triangle for something like tan(tan(5pi/4)), but that was given.  Wolframalpha gave me the answers, but I don't remeber how to actually solve them, sorry

it's ok. never mind.
