Using the Action Menu
S
normal
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
=
x
3
at
x
= 2
Menu Item: [Action][Calculation][normal]
S
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 [
) ]
Example: To determine the arc length for
y
=
x
3
—
2
from
x
= 0 to
x
= 4
Menu Item: [Action][Calculation][arcLen]
S
rangeAppoint
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
=
P
,
x
= 2
P
,
x
= 3
P
} that belong(s) to the
closed range 0

S
mod
Function: Returns the remainder when one expression is divided by another expression.
Syntax: mod ({Exp/List} -1, {Exp/List} -2 [ ) ]
Example: To determine the remainder when 26 is divided by 3 (26mod3)
Menu Item: [Action][Calculation][mod]
S
tanLine
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
