Calculus
Related Rates Calculator
Compute the rate of area change of a circle whose radius grows at a constant rate, evaluated after a given elapsed time. Returns dA/dt = 2π · r(t) · (dr/dt) at the chosen moment.

Calculus
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.
