41+ Conic Sections Parabola Equation Pictures. Introduction, finding information from the equation, finding the equation from information, word problems & calculators. The circle is a special case of the ellipse.

A section (or slice) through a cone. To determine the conic section by inspection, complete any squares that are necessary, so that the variables are on one side and the constant is on the right hand side. Parabolas, circles, ellipses, and hyperbolas.

Did you know that by taking different slices through a cone you can create a circle, an ellipse, a so the general equation that covers all conic sections is:

We have worked with parabolas a parabola is the set of points that are equally distant from a focus point and the directrix, a fixed line. Parabolas can be the only conic sections that are considered functions because they pass the vertical line test. The second equation represents a parabola that opens either to the left or to the right. I have trouble grasping parabolas, and mainly the cartesian equations describing the,.
