==== Directrix ==== A Quadratic Simulator 100% Pen To move the focus (green dot), use W (up) & S (down) To move the vertex (blue dot), use the arrows To move the hover (yellow dot), use A (left) & D (right) Inspired by my math teacher. Try to figure out what the use of the directrix (purple line) is! If you have any suggestions, let me know. Currently thinking of adding drag controls, being able to see the equation in ax^2+bx+c=0 and a(x-h)^2+k=0 form, and literally whatever else. = Update 11/22/19 = Oh I forgot about this haha. Thanks for the comments and things. If you want more math projects, leave suggestions for those in the comments.
