Using the Transformation Submenu

The [Transformation] submenu contains commands for expression transformation, like “expand” and “factor”.

uapprox [Action][Transformation][approx]

Function: Transforms an expression into a numerical approximation.

Syntax: approx (Exp/Eq/Ineq/List/Mat [ ) ]

Example: To obtain the numerical value of '2

usimplify [Action][Transformation][simplify]

Function: Simplifies an expression.

Syntax: simplify (Exp/Eq/Ineq/List/Mat [ ) ]

Example: To simplify (15'3 + 26)^(1/3)

uexpand [Action][Transformation][expand]

Function: Expands an expression.

Syntax: expand (Exp/Eq/Ineq/List/Mat [ ) ]

expand (Exp,variable [ ) ]

•If you specify a variable, Exp is decomposed into partial fractions, with respect to the variable.

Example: To expand (x + 2)2

ufactor [Action][Transformation][factor][factor]

Function: Factors an expression.

Syntax: factor (Exp/Eq/Ineq/List/Mat [ ) ]

Example: To factor x2 4x + 4
