Conic Section and Remember the Basics

We were using this info to find the equations and the graphs of the conic sections: ellipses, hyperbola, and parabola. The vertex are the farthest most point(s) on the line. There are major and minor axes with ellipses. A and B are the radii for the axes. When finding the slope, remember to use y2-y1/x2-x1. To find point slope form, plug in the point and slope into y-y1=m(x-x1). Then simplify to YMCA aka Y=mx+b, where m is the slope and b is the y intercept. Remember to identify the center first(opposite signs). Identify A and B and a^2 and b^2. For the focal distance in parabolas, use F=(1)/4A. For the A that represents direction in parabolas, use A=(1)/4F. Also, the foci is the same distance from the conic, as the conic is from the directrix. To find the slope of a hyperbola just rise over run the box from the center. I will go into more detail later!
