ulcm

Function: Returns the least common multiple of two expressions.

Syntax: lcm (Exp/List-1, Exp/List-2 [ ) ]

Example: To obtain the least common multiple of x2 – 1 and x2 + 2x – 3

urangeAppoint

Function: Finds an expression or value that satisfies a condition in a specified range.

Syntax: rangeAppoint (Exp/Eq/List, start value, end value [ ) ]

•When using an equation (Eq) for the first argument, input the equation using the syntax Var = Exp. Evaluation will not be possible if any other syntax is used.

Example: To find the expression(s) in the list {x = π, x = 2π, x = 3π} that belong(s) to the closed range 0 < x < 5

[rangeAppoint]

Example: To find the “n” that satisfies the condition 0 < n ⋅ π < 5

Menu Item: [Action][Calculation][rangeAppoint]

udenominator

Function: Extracts the denominator of a fraction.

Syntax: denominator (Exp/List [ ) ]

Example: To extract the denominator of the fraction (y – 2)/(x + 1)
