Divergence and Curl Calculator

This example demonstrates the calculation and visualization of divergence and curl in vector fields, involving core concepts like divergence, curl, and gradient from vector calculus. It constructs input vector fields F1, F2, F3 and computes objects such as dF1x, dF1y, dF1z, Div, Curli using GeoGebra commands like Textfield and Line. Suitable for university students in mathematics or physics and learners interested in vector analysis.
