Complex Number and Geometry Demonstration

This example demonstrates the representation of the complex number c = 0.28 + 0.54i in the complex plane and its related geometric properties. Core mathematical concepts include complex numbers, unit circle, centroid, tangent, and differential equations. GeoGebra commands and objects used in the construction include First, A, A1, c, s, A2-A20, L, R, b, tekst23, A21, lijst2, B, C, raster, knop1, D, E, F, G, afbeelding1, afbeelding2, etc. It is suitable for high school and above mathematics learners to understand the connection between complex numbers and geometric figures.
