Second Derivative Description Second Derivative


Press to view the calculus menu, then to select the second derivative option, der2.

The syntax is: der2( expression,variable [,value] )

The second derivative option algebraically finds the second derivative of expression with respect to variable at value. If value is omitted, the current value of variable is used.




Note: Unfortunately, the TI cannot differentiate some functions algebraically. For these functions use the less accurate numerical differentiation option nDer twice.
