# Simplifying complex exponentials: tsimplify

### 5.24.9 Simplifying complex exponentials: tsimplify

The tsimplify command 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.

- tsimplify takes one argument:
  expr, an expression.
- tsimplify(expr) returns a (possibly) simplified version of expr.

#### Example.

Input:

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

Output:

⎛ ⎝ | ei x | ⎞ ⎠ | 4+1

⎛ ⎝ | ei x | ⎞ ⎠ | 2
