# What kind of functions have vertical asymptotes?

May 5, 2015

There is no one kind of function that has vertical asymptotes.

Rational functions have vertical asymptotes if, after reducing the ratio the denominator can be made zero.

All of the trigonometric functions except sine and cosine have vertical asymptotes.

Logarithmic functions have vertical asymptotes.

Those are the kinds students in calculus classes are most likely to encounter.
