Answer:
[tex]y=\cos(x)[/tex]
Step-by-step explanation:
The function [tex]y=secx=\frac{1}{cosx}[/tex].
There is a vertical asymptote at [tex]cosx=0[/tex]
The function [tex]y=cotx=\frac{cosx}{sinx}[/tex].
There is a vertical asymptote at [tex]sinx=0[/tex]
The function [tex]y=cscx=\frac{1}{sinx}[/tex].
There is a vertical asymptote at [tex]sinx=0[/tex]
The function [tex]y=cosx[/tex].
has no asymptote
