asymptote
(noun)
a straight line which a curve approaches arbitrarily closely, as they go to infinity
Examples of asymptote in the following topics:
-
Horizontal Asymptotes and Limits at Infinity
- In the first case, $ƒ(x)$ has $y = c$ as asymptote when $x$ tends toward $- \infty$, and in the second that $ƒ(x)$ has $y = c$ as an asymptote as $x$ tends toward $+ \infty$.
- More general type of asymptotes can be defined as the oblique asymptote case.
- Only open curves that have some infinite branch, can have an asymptote.
- No closed curve can have an asymptote.
- The graph of a function can have two horizontal asymptotes.
-
Infinite Limits
- If the limit at infinity exists, it represents a horizontal asymptote at $y = L$.
- Polynomials do not have horizontal asymptotes; such asymptotes may however occur with rational functions.
-
Curve Sketching
- Determine the asymptotes of the curve.
- Also determine from which side the curve approaches the asymptotes and where the asymptotes intersect the curve.
-
Improper Integrals
- An improper Riemann integral of the second kind.The integral may fail to exist because of a vertical asymptote in the function.
