Using the Action Menu
uexpand
Function: Expands an expression.
Syntax: expand (Exp/Eq/Ineq/List/Mat [ ) ]
expand (Exp,variable [ ) ]
•Ineq (inequality) includes the “≠” (not equal to) relational operator.
•If you specify a variable, Exp is decomposed into partial fractions, with respect to the variable.
Example: To expand (x + 2)2
Menu Item: [Action][Transformation][expand]
1
Example: To decompose (x4 – 1) into partial fractions, with respect to x
Menu Item: [Action][Transformation][expand]
ufactor
Function: Factors an expression.
Syntax: factor (Exp/Eq/Ineq/List/Mat [ ) ]
•Ineq (inequality) includes the “≠” (not equal to) relational operator. Example: To factor x2 4x + 4
Menu Item: [Action][Transformation][factor]
urFactor
Function: Factors an expression up to its roots, if any.
Syntax: rFactor (Exp/Eq/Ineq/List/Mat [ ) ]
•Ineq (inequality) includes the “≠” (not equal to) relational operator. Example: To factor x2 3
Menu Item: [Action][Transformation][rFactor]
ufactorOut
Function: Factors out an expression with respect to a specified factor.
Syntax: factorOut (Exp/Eq/Ineq/List/Mat, Exp [ ) ]
•Ineq (inequality) includes the “≠” (not equal to) relational operator. Example: To factor “a” out ax2 + bx + c
Menu Item: [Action][Transformation][factorOut]
