u diff
Function: Differentiates an expression with respect to a specific variable.
Syntax: diff(Exp/List[,variable] [ ) ]
diff(Exp/List,variable,order[,a] [ ) ]
• “a” is the point for which you want to determine the derivative.
• “order” = 1 when you use the following syntax: diff(Exp/List[,variable][ ) ]. The default
variable is “x” when “variable” is omitted.
Example: To differentiate x
6
with respect to x
Menu Item: [Action][Calculation][diff]
Example: To find the second derivative of x
6
with respect to x
Menu Item: [Action][Calculation][diff]
Example: To find the second derivative of x

u toDMS
Function: Transforms a degrees-only value into its equivalent DMS format value.
Syntax: toDMS (Exp/List [ ) ]
Example: To transform 3.085 degrees into its equivalent DMS format value
Menu Item: [Action][Transformation][toDMS]
