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
