3D Models for Teaching Integrals: Visual Examples for the Classroom

This collection of 3D models is designed as an example for teaching mathematics, helping to make the concept of integrals easier to understand. The models show the area under a curve, Riemann sums with different rectangle widths, and solid shapes created by rotation to explain volume calculation. They are made specifically for classroom use to visually demonstrate abstract concepts. These models are not meant for real calculations but serve as educational tools to support learning through practical examples.
