Hi! How do you write the LaTeX code for the secant, cosecant, and cotangent hyperbolic functions?(adsbygoogle = window.adsbygoogle || []).push({});

I tried using \sech, \csch, and \coth but I am getting an error when I run the latex program. It is giving me a undefiend control sequence message? Is there a package I need to include in my .tex file to have those hyperbolic functions?

Thanks
