What is arctan(0)?!
I tired using my calculator (its a ti-83 plus) I hit [sec] button then [tan] then [ 0 ] and [ ) ] and it gives me 0 as answer It is in rad mode too (deg mode is same results)
I tried using the google calculator and it gives me 0 also!
http://www.google.com/search?hl=en&q=arctan(0)
BUT my math book says its pie!
Then it tried tan(pi) and indeed that does = 0!
WHY!??!? doenst arctan(0) = pi?
Another question
What is arctan(1/0) ? doens that = impossible?? (if i use my calc it says can't divide by 0)
However the answer is pi/2?!??! WHYYY
Thanks for the help
