you need to factorise which is inside of the arctan function.

i dont get what you are saying, but when i simplify, then i get

lim x -> 2 arctan(x+2/5x)

then i put in 2, and get 4/10, then i do arctan of that and get 21.804

but this is the wrong answer, how do i properly do this..???(Angry)(Angry) - October 6th 2009, 01:01 PMtonio
