How to Find Horizontal Asymptotes
In this example there is a vertical asymptote at x 3 and a horizontal asymptote at y 1. Here are the vertical asymptotes of trigonometric functions. Shortcut To Find Horizontal Asymptotes Of Rational Functions Youtube Rational Function Physics And Mathematics Numerator The curves approach these asymptotes but never cross them. . But note that there cannot be a vertical asymptote at x some number if there is a hole at the same number. Here are the two steps to follow. This next step involves polynomial division. Read Solving polynomials to learn how to find the roots. So to find the vertical asymptotes of a rational function. But each of the other 4 trigonometric functions tan csc sec cot have vertical asymptotes. The curves approach these asymptotes but never visit them. In this section we deal with horizontal and oblique asymptotes. There are three kinds of asymptotes. We begin by examini...
