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
x
variable is "
" when "variable" is omitted.

impDiff
Function: Differentiates an equation or expression in implicit form with respect to a
specific variable.
Syntax: impDiff(Eq/Exp/List, independent variable, dependent variable)
Example: To find y ' using implicit differentiation
Menu Item: [Action][Calculation][impDiff]
Example: To find y " given y ' = − x / y

Important!
The derivative symbol (') cannot be used in the argument of "impDiff(". Trying to use a
derivative symbol would result in a Wrong Argument Type error.
