Asymptote Calculator

Find vertical, horizontal, and oblique asymptotes for rational and other functions.

Function Type

Numerator coefficients

x^1

x^0

Denominator coefficients

x^1

x^0

Function:

f(x) = (1x) / (1x + -1)

Vertical Asymptotes:

x = 1

Horizontal Asymptote:

y = 1

Vertical:

Where denominator = 0 (and numerator ≠ 0)

Horizontal:

deg(num) < deg(den): y = 0

deg(num) = deg(den): y = leading coefficients ratio

Oblique:

deg(num) = deg(den) + 1: perform division
