30.7.6 Looking Back at the Coordinate Method: Geometry Is Algebra
Core idea
Every figure has been translated into an equation to compute, and this back-and-forth between shape and symbol quietly seeds the imaginary axis ahead.
Module goal. Introduce the parabola and, through equal point-line distance and eccentricity, thread all three curves into one system, wrapping up the coordinate method.
