In Mathematica, arguments of functions are enclosed in square brackets [] and NOT in parentheses () -- unless, that is, you're trying to use TraditionalForm input (which can be dangerous due to its possible ambiguity). So you want: Plot[Cosh[x],{x,-1,1}] In what you had, the parentheses are just grouping symbols, so the expression fed to Plot is a product of the symbols Cosh and x. dimzi101 at gmail.com wrote: > When trying this: > > Plot[Cosh(x), {x, -1, 1}] > > I constantly get errors! > > Im trying to plot some catenaries using table (for various values), and > this is stopping me from doing so. > > Any suggestions? > > -- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
