It is something from https://mathematica.stackexchange.com/questions/114634/simplifying-polynomials-with-conditions-on-variables, that intend to minimize the number of variables. The problem is the usage of ``Solve". I know how to solve equations,...
Thanks for your reply. It is an enlightening answer. Syed also replied this question at StackExchange(see the link attached above) that might be a solution.
Thanks. It is worth to try.
Firstly, the Mathematica code is given as ``` A = -2/3000; F = (7 Sinh[\[Xi] - 0.3 t])/(30 Cosh[\[Xi] - 0.3 t]) - ( 23 Sinh[\[Xi] - 0.3 t])/(60 (Cosh[\[Xi] - 0.3 t])^3) + ( 7 Sinh[\[Xi] - 0.1 t])/(15 Cosh[\[Xi] - 0.1 t]) - ( 23...
Thank you for your notification, I will pay attention to this matter.
Sorry for the mistake, it does function.
