Using the Action Menu

ueliminate

Function: Solves one equation with respect to a variable, and then replaces the same variable in another expression with the obtained result.

Syntax: eliminate (Eq/Ineq/List-1, variable, Eq-2 [ ) ]

• Ineq (inequality) includes the “≠” (not equal to) relational operator.

Example: To transform y = 2x + 3 to x =, and substitute the result into 2x + 3y = 5

uabsExpand

Function: Divides an absolute value expression into formulas without absolute value.

Syntax: absExpand (Eq/Ineq [ ) ]

• Ineq (inequality) includes the “≠” (not equal to) relational operator. Example: To remove the absolute value from 2x – 3 = 9

uandConnect

Function: Combines two equations or inequalities into a single expression.

Syntax: andConnect (Eq/Ineq-1, Eq/Ineq-2 [ ) ]

•Ineq (inequality) includes the “≠” (not equal to) relational operator.

Example: To rewrite x > –1 and x < 3 into a single inequality

ugetRight

Function: Extracts the right-side elements of an equation or inequality.

Syntax: getRight (Eq/Ineq/List [ ) ]

•Ineq (inequality) includes the “≠” (not equal to) relational operator.

Example: To extract the right side elements of y = 2x2 + 3x + 5

ugetLeft

Function: Extracts the left-side elements of an equation or inequality.

Syntax: getLeft (Eq/Ineq/List [ ) ]

• Ineq (inequality) includes the “≠” (not equal to) relational operator. Example: To extract the left side elements of y = 2x2 + 3x + 5
