urewrite

Function: Moves the right side elements of an equation or inequality to the left side.

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

•Ineq (inequality) includes the “≠” (not equal to) relational operator. Example: To move the right side elements of x + 3 = 5x – x2 to the left side Menu Item: [Action][Equation/Inequality][rewrite]

uexchange

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

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

•Ineq (inequality) includes the “≠” (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]

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

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

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