Analytic Geometry of Parabola
Define, create and explore parabolas, including their foci and directrices.
Dynamical change of parabolas, with their foci and directrices, by changing the parameters of their equations.
Display and explore the distances between the focus, points on the graphs and the directrix, including sums or differences and/or ratios of distances, to learn the properties and characteristics of parabolas and their geometrical representation. The following screenshots were designed to meet the pedagogical approach needed for teaching and learning of these topics:
Topic 1 - Parabola with focus on the x-axis            

Topic 2 - Parabola with focus on the y-axis

Dynamic movable tools, such as: Points, Segments, Straight Lines, Parallels, Perpendiculars, Tangents, Chords, Perpendiculars from a point, Tangents through an external point, Angles and Angle Bisectors.
Tracing while obtaining updated quantitative information for each location, and the dynamic tools, including the relevant equations.

Quantitative coordinate system (scales), fully user controlled by zooming in/out, dragging the axes and changing the scales.
