Cube Octahedron Volume Calculation and Integral Demonstration

This example demonstrates the volume calculation and integral demonstration of a cube octahedron. It involves core mathematical concepts such as volume, arithmetic operations, quadratic functions, upper and lower sum or Riemann sum, and complex numbers. The construction uses GeoGebra commands like Sequence and objects k, r, a, b, c, d, h, L, S. It is suitable for high school and above students to learn and understand solid geometry and calculus concepts.
