The Simplify Command

The Simplify command acts on a wide variety of expressions. It contains functionality that reduces expressions to a simpler form. The keystroke for the Simplify command is the "s" key.

The functionality in the Simplify command with the Trig, Math and Code libraries installed includes simplification of Boolean expression, algebraic expressions and expressions involving trig functions.

Note that the simplify command doesn't fully evaluate numeric expressions. It will evaluate integer expressions like

1 + 3 + 7

and it will simplify expressions like


but the simplifier will leave expressions like

1/2 * (x + 1).

The Simplify command acts recursively on all terms of the highlighted expression, so applying the Simplify command can result in multiple simplifications to an expression.
