Geogebra Demonstration of Complex Number c = -1.25 + 0i

This example demonstrates the geometric representation of the complex number c = -1.25 + 0i in the complex plane, including its modulus and argument. It involves core concepts like complex numbers, complex plane, Euler's formula, and geometric operations. The construction uses GeoGebra commands such as First to manipulate objects A, A1, c, s, A2-A20, L, R, b, tekst23, A21, lijst2, B, C, raster, knop1, D, E, F, G, afbeelding1, afbeelding2. Suitable for high school mathematics education to understand the visual representation and properties of complex numbers.
