Compare calculators

Both calculators run independently — change the inputs on either side to compare results.

Numerical Derivative Calculator

Compute the derivative of a power function f(x) = c·x^n + k at a chosen point using either the analytical power rule or a numerical finite-difference approximation. Select 'analytical', 'forward', or 'central' to compare exact and approximate results.
