Pi is a number that is approximately equal to 3.14. It is the number you get if you divide the circumference of any circle by its diameter. It's the same for all circles. You can approximate pi for yourself by taking some circular things like the tops of jars and CD's and frisbees and measuring their diameter and their circumference.
Geometric Definition. Definition: A parabola is the set of points in the plane that are equidistant from a point (the focus) and a line (the directrix.). The following exercise should help convince you that this definition yields the parabolas you are familiar with. Exercise: Given a focus at (0,1) and a directrix y=-1, find the equation of the parabola. How to do it: draw a figure showing a generic point P on the parabola, with coordinates (x,y).
