Homework Equations
The Attempt at a Solution
Hi guys.So I'm having trouble proving this limits(all limits that i need to prove that they equal +/- ∞) , all that I've learned in calculus so far at school is these e proprieties
limit when x→∞ from xn=L ⇔ [itex]\forall[/itex]ε>0 [itex]\exists[/itex]nε so that for [itex]\forall[/itex] n≥nε we have |xn-L|<ε
the second one is when limit whenx→∞ from xn= +∞ it's the same except the last part where you don't have |xn-L|<ε but we have xn≥ε
fot the third one limit when x→∞ from xn= -∞ when xn≤-ε
TY!
