u 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 "≠" (not equal to) relational operator.
Example: To transform
Menu Item: [Action][Equation/Inequality][eliminate]
u absExpand
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 2
Menu Item: [Action][Equation/Inequality][absExpand]
u andConnect
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
Menu Item: [Action][Equation/Inequality][andConnect]
u getRight
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
Menu Item: [Action][Equation/Inequality][getRight]
u getLeft
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
Menu Item: [Action][Equation/Inequality][getLeft]
