Cylinder Problem

This example demonstrates the geometric relationship between a cylinder, right triangles, quadratic equations, ellipses, and tangent lines. It involves core math concepts like cylinder construction, right triangle properties, quadratic equation solving, ellipse equations, and tangent line calculation. The construction uses commands/objects like eq1, f, A, eq2 for function definition, point marking, and equation plotting. Suitable for high school mathematics teaching, focusing on the integration of analytical geometry and solid geometry.
