Sphere with Unit Circle, Complex Numbers, Logarithmic Functions and Sequences

This GeoGebra example constructs a three-dimensional sphere and integrates the unit circle, complex numbers, logarithmic functions, and sequences within or related to the spherical space. It demonstrates how these mathematical objects can be visualized in 3D, highlighting the geometric representation of complex numbers on the unit circle, the shape of logarithmic curves, and discrete sequence points. The construction uses commands such as PointIn, Ray, Point, and Vector, creating objects like points A, B, C, D, E, F, vector u, ray g, and additional elements a, b, f. Suitable for high school to university students, this example serves as an interactive tool for exploring the interplay between 3D geometry, complex analysis, function graphing, and sequence visualization, ideal for classroom demonstrations or self-directed mathematical inquiry.
