### 2.23.9 Simplify complex exponentials : `tsimplify`

`tsimplify` simplifies transcendental expressions
by rewriting the expression with complex exponentials.

It is a good idea to try other simplification instructions
and call `tsimplify` if they do not work.

Input :

`tsimplify((sin(7*x)+sin(3*x))/sin(5*x))`

Output :

`((exp((i)*x))``^`

`4+1)/(exp((i)*x))``^`
