apply simplification rules to an expression
The simplify command is used to apply simplification rules to an expression.
The simplify routine searches the expression for function calls, square roots, radicals, and powers and invokes the appropriate simplification procedures.
For detailed information on the simplify command, see simplify/details.
Simplifying exponentials and logarithms
Controlling which simplification rules to use
When trig is specified as the second argument, only the trigonometric expressions are simplified.
Using the assume option
When you use the assume=property option as the last argument, all the indeterminate variables in expr are assumed to have the property when simplifying the expression. In the following example, x is assumed to be positive. For more information, see the simplify/details page.
Simplifying with respect to side relations
The command simplify can perform simplification with respect to side relations. For details, see simplify/siderels.
eqns ≔ sin⁡x2+cos⁡x2=1:
e ≔ sin⁡x3−11⁢sin⁡x2⁢cos⁡x+3⁢cos⁡x3−sin⁡x⁢cos⁡x+2
Simplify with respect to cos(x) first.
