Re: [HP-Prime CAS] Automatic Simplification (Direct Answer) - Thomas Klemm - 07-25-2013 Still the denominator could be simplified: Sqrt[(Exp[x] + Exp[-x])^2 - (Exp[x] - Exp[-x])^2] = 2 Re: [HP-Prime CAS] Automatic Simplification (Direct Answer) - CompSystems - 07-25-2013 (exp(x)+exp(-x))/(Sqrt ( (exp(x)+exp(-x))^2-(exp(x)-exp(-x))^2 ) ) Re: [HP-Prime CAS] Automatic Simplification (Direct Answer) - Gilles Carpentier - 07-26-2013 EDIT forget all of this ... my error, I read n! instead of n .....
