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
Menu Item: [Action][Calculation] [rangeAppoint]
Example: To find the “n” that satisfies the condition 0 <n ⋅ π <5

umod
Function: Returns the remainder when one expression is divided by another expression.
Syntax: mod ({Exp/List}
Example: To determine the remainder when 26 is divided by 3 (26mod3)
Menu Item: [Action][Calculation][mod]
utanLine
Function: Returns the right side of the equation for the tangent line (y = ‘expression’) to the curve at the specified point.
Syntax: tanLine (Exp/List, variable, variable value at point of tangency [ ) ]
Example: To determine the function of the line tangent to y = x3 at x = 2
Menu Item: [Action][Calculation][tanLine]
unormal
Function: Returns the right side of the equation for the line normal (y = ‘expression’) to the curve at the specified point.
Syntax: normal (Exp/List, variable, variable value at point of normal [ ) ]
Example: To determine the function of the line normal to y = x3 at x = 2
Menu Item: [Action][Calculation][normal]
u arcLen
Function: Returns the arc length of an expression from a start value to an end value with respect to a specified variable.
Syntax: arcLen (Exp/List, variable, start value, end value [ ) ]
3 | from x = 0 to x = 4 |
