Finding limit as x approaches infinity

WebJul 15, 2015 · lim x→−∞ p(x) = lim x→ −∞ anxn This fact is really saying that when we take a limit at infinity for a polynomial, all we have to do is look at the term with the largest power and ask what that term is doing in the limit. If a is positive and n is even, then anxn is always positive, and lim x→−∞ p(x) = lim x→ −∞ anxn = ∞ WebOct 5, 2014 · 1 Answer Wataru Oct 5, 2014 Let us figure this out from our knowledge about tanx. We know: as x → π 2 −, tanx → +∞ Since arctanx is the inverse function of tanx, − π 2 < x < π 2, we can swapping the relationship above to obtain: as x → +∞, arctanx → π 2 − Hence, lim x→∞ arctanx = π 2. I hope that this was helpful. Answer link
