Conic Sections For Dummies

Conics are curved algebraic forms that come from slicing a cone with a plane.

Conic sections for dummies. The first thing you need to do is make the denominator begin with 1. The four basic types of conics are parabolas ellipses circles and hyperbolas. If e 1 the conic section is a parabola.

Part of algebra ii for dummies cheat sheet. Parametric form defines both the x and the y variables of conic sections in terms of a third arbitrary variable called the parameter which is usually represented by t you can find values for both x and y by plugging values for t into the parametric equations. Use these equations to graph algebraic conics such as circles ellipses parabolas and hyperbolas.

In mathematics a conic section or simply conic is a curve obtained as the intersection of the surface of a cone with a plane the three types of conic section are the hyperbola the parabola and the ellipse. For example take a look at 3 x 2 12 x. The steps of the process are as follows.

Conic sections can be described or illustrated with exactly what their name suggests. Then picture some clever highway engineer placing one cone on top of the other tip to tip. When the equation of a conic section isn t written in its standard form completing the square is the only way to convert the equation to its standard form.

If e 1 the conic section is a hyperbola. Often this information is more important than the graph itself. You have to indicate where the center vertices major and minor axes and foci are located.

Circle ellipse parabola and hyperbola. Factor the leading. How to identify the four conic sections in equation form.
