Ellipse theorems
WebSuppose there is an ellipse with the following equation, $$\frac{x^2}{a^2}+\frac{y^2}{b^2}=1$$ Then we could parameterize it into $$x=a\cos t, … WebFor the parabola, the standard form has the focus on the x-axis at the point (a, 0) and the directrix is the line with equation x = −a. In standard form, the parabola will always pass through the origin. Circle: x 2+y2=a2. Ellipse: x 2 /a 2 …

Pascal's theorem has a short proof using the Cayley–Bacharach theorem that given any 8 points in general position, there is a unique ninth point such that all cubics through the first 8 also pass through the ninth point. In particular, if 2 general cubics intersect in 8 points then any other cubic through the same 8 points meets the ninth point of intersection of the first two cubics.
