Numerical Derivative

The TI-30X Pro MathPrint™ calculates the (approximate) numerical derivative of an
expression at a point given a tolerance for the numerical method. (See the About the
Numerical Derivative at a Point
MathPrint™ Mode
% A pastes the numerical derivative template from the keypad to calculate the
numerical derivative with the default tolerance H is 1EM5.
Example
% A % A

To change the default tolerance, H, and observe how the tolerance plays a role in the
numerical solution, paste the numerical derivative from the menu location, d
, where the numerical derivative template will paste with the option to
