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 section for more information.)
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
z F T 5 z " "
M 1 <
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
MATH 7:nDeriv(, where the numerical derivative template will paste with the option to
modify the tolerance as needed for an investigation of the numerical derivative result.
