1. What is a Conic Section?

A conic section is a curve obtained as the intersection of a cone with a plane. The four types are circles, ellipses, parabolas, and hyperbolas. The general second-degree equation represents all these conic sections.

2. How Does the Calculator Work?

The calculator uses the discriminant of the general conic equation:

Where:

• If \( B^2 - 4AC < 0 \): Ellipse (or circle if A = C and B = 0)
• If \( B^2 - 4AC = 0 \): Parabola
• If \( B^2 - 4AC > 0 \): Hyperbola

Explanation: The discriminant determines the nature of the conic section represented by the equation.

3. Importance of Conic Section Analysis

Details: Identifying conic sections is fundamental in mathematics, physics, engineering, and astronomy as they describe many natural phenomena and man-made structures.

4. Using the Calculator

Tips: Enter the coefficients (A-F) of your conic equation. The calculator will determine the type of conic section represented by these coefficients.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between a circle and an ellipse?
A: A circle is a special case of an ellipse where the two axes are equal in length.

Q2: How can I tell if a parabola opens vertically or horizontally?
A: This depends on which squared term is present in the equation (x² or y²) when B = 0.

Q3: What does the xy term (B coefficient) do?
A: The xy term indicates the conic section is rotated relative to the coordinate axes.

Q4: Can all these conics be formed by intersecting a cone?
A: Yes, all four types can be formed by intersecting a double cone with a plane at different angles.

Q5: What practical applications do conic sections have?
A: They're used in optics (lenses/mirrors), astronomy (orbits), architecture (arches), and many engineering applications.
