I'm new to Mathematica and I've only been using it for about a week.
How can I find the roots of equations like Cosh[x]= x^2 to anything more than the default accuracy? If I type FindRoot[Cosh[x]==x^2,{x,1}] I just get {x->1.62135}. Is there anything I can add to get a numerical approximation to, say, 20 digits?
Thanks.
