Using the Action Menu

Sexchange

Function: Swaps the right-side and left-side elements of an equation or inequality.

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

• Ineq (inequality) includes the “ξ” (not equal to) relational operator. Example: To swap the left-side and right-side elements of 3 > 5x – 2y Menu Item: [Action][Equation/Inequality][exchange]

Seliminate

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 “ξ” (not equal to) relational operator.

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

Menu Item: [Action][Equation/Inequality][eliminate]

SabsExpand

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

Syntax: absExpand(Eq/Ineq [ ) ]

• Ineq (inequality) includes the “ξ” (not equal to) relational operator. Example: To remove the absolute value from ƒ2x – 3 ƒ = 9

Menu Item: [Action][Equation/Inequality][absExpand]

SandConnect

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

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

• Ineq (inequality) includes the “ξ” (not equal to) relational operator. Example: To rewrite x > –1 and x < 3 into a single inequality Menu Item: [Action][Equation/Inequality][andConnect]

SgetRight

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

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

• Ineq (inequality) includes the “ξ” (not equal to) relational operator. Example: To extract the right side elements of y = 2x2 + 3x + 5 Menu Item: [Action][Equation/Inequality][getRight]
