Using the Action Menu
S exchange
Function: Swaps the right-side and left-side elements of an equation or inequality.
Syntax: exchange(Eq/Ineq/List [ ) ]
• Ineq (inequality) includes the “ x” (not equal to) relational operator.
Example: To swap the left-side and right-side elements of 3 > 5 x – 2 y
Menu Item: [Action][Equation/Inequality][exchange]
S eliminate
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 “ x” (not equal to) relational operator.
Example: To transform y = 2 x + 3 to x =, and substitute the result into 2 x + 3 y = 5
Menu Item: [Action][Equation/Inequality][eliminate]
S absExpand
Function: Divides an absolute value expression into formulas without absolute value.
Syntax: absExpand(Eq/Ineq [ ) ]
• Ineq (inequality) includes the “ x” (not equal to) relational operator.
Example: To remove the absolute value from ¦2 x – 3 ¦ = 9
Menu Item: [Action][Equation/Inequality][absExpand]
S andConnect
Function: Combines two equations or inequalities into a single expression.
Syntax: andConnect(Eq/Ineq-1, Eq/Ineq-2 [ ) ]
• Ineq (inequality) includes the “ x” (not equal to) relational operator.
Example: To rewrite x > –1 and x < 3 into a single inequality
Menu Item: [Action][Equation/Inequality][andConnect]
S getRight
Function: Extracts the right-side elements of an equation or inequality.
Syntax: getRight(Eq/Ineq/List [ ) ]
• Ineq (inequality) includes the “ x” (not equal to) relational operator.
Example: To extract the right side elements of y = 2 x 2 + 3 x + 5
