Complex Functions for a Newton's-method root
Built for first responders planning or training for real incidents. Run fast what-if scenarios for response planning and training — no software to install in the field. Simulate a Newton's-method root live below — adjust the inputs and watch it respond, right in your browser.

Domain coloring maps each complex output to a color: hue = phase (argument), brightness = magnitude. Zeros are dark, poles are bright.

Reading this result: z² doubles every angle, so the hue wheel wraps twice around the single zero at the origin — a double root shows as two full color cycles.
