This GeoGebra applet demonstrates the modular surface of the complex function f(z) = 1 / (1 + z²). It provides a 3D visualization of the absolute value |f(z)| over the complex plane. The interactive model clearly illustrates the singularities at the poles z = ±i and the overall geometric properties, making it an excellent tool for studying complex analysis.
