6.23.5  Simplifying: simplify

The simplify command simplifies expressions. As with all automatic simplifications, do not expect miracles; you will have to use specific rewriting rules if it does not work.

• simplify takes one argument:
  expr, an expression.
• simplify(expr) returns the simplified version of expr.

Example.

Warning.
simplify is more efficient in radian mode (which you can turn on, if it isn’t already, by checking radian in the cas configuration or inputting angle_radian:=1, see Section 3.5.3).
