Explanation

Conic sections are curves formed when a plane cuts a cone.

There are four main types:

1. Circle

2. Ellipse

3. Parabola

4. Hyperbola

Each conic has a standard equation and geometric meaning.

Examples of standard forms:

• Circle: (x − h)² + (y − k)² = r²

• Ellipse: (x − h)²/a² + (y − k)²/b² = 1

• Hyperbola: (x − h)²/a² − (y − k)²/b² = 1

Conics are used in:

• Astronomy

• Physics

• Engineering

• Architecture
