What is a conic section?

Back

A conic section is a curve obtained by intersecting a cone with a plane. The four types of conic sections are circles, ellipses, parabolas, and hyperbolas.

What is the standard form of the equation of an ellipse?

Back

The standard form of the equation of an ellipse centered at (h, k) is (x - h)²/a² + (y - k)²/b² = 1, where a and b are the semi-major and semi-minor axes.

What is the standard form of the equation of a hyperbola?

Back

The standard form of the equation of a hyperbola centered at (h, k) is (x - h)²/a² - (y - k)²/b² = 1 or (y - k)²/b² - (x - h)²/a² = 1.

What is the definition of a parabola?

Back

A parabola is a conic section that is formed by the intersection of a cone and a plane parallel to its side. It can be represented by the equation y = ax² + bx + c.

How do you identify a circle from its equation?

Back

A circle can be identified from its equation if it is in the form (x - h)² + (y - k)² = r², where r is the radius.

What is the difference between an ellipse and a circle?

Back

An ellipse is a stretched circle, defined by two focal points, while a circle is a special case of an ellipse where both foci coincide at the center.
