Part I: Infinite Limits: vertical asymptote at x=0. online.math.uh.edu/HoustonACT/Greg_Kelly.../Calc02_2.ppt
“On the contrary, it tells HOW the limit FAILS to exist.” IMPORTANT NOTE: The equal sign in the statement does NOT mean the limit exists! “On the contrary, it tells HOW the limit FAILS to exist.” Page 80 Dr. Larson & Dr. Hostetler www.vcsc.k12.in.us/lincoln/math/CaseNotes/.../InfiniteLimits.ppt
Definition of a Vertical Asymptote If f(x) approaches infinity or negative infinity as x approaches c from the left or right, then x = c is a vertical asymptote of f. www.vcsc.k12.in.us/lincoln/math/CaseNotes/.../InfiniteLimits.ppt
Digging deeper… Infinity is a very special idea. We know we can't reach it, but we can still try to work out the value of functions that have infinity in them. http://www.mathsisfun.com/calculus/limits-infinity.html
Question: What is the value of 1/∞ ? Answer: We don't know! Maybe we could say that 1/∞ = 0, ... but if we divide 1 into infinite pieces and they end up 0 each, what happened to the 1? In fact 1/∞ is known to be undefined. http://www.mathsisfun.com/calculus/limits-infinity.html

The limit of 1/x as x approaches Infinity is 0 Furthermore: http://www.mathsisfun.com/calculus/limits-infinity.html
Limits at Infinity Divide through by the highest power of x in the denominator Simplify Substitute 0 for 1/xn www.mrsantowski.com/MCB4U/Notes/PowerPointNotes/BCC016.ppt
