WebMay 11, 2016 · The general equation is y ′ = m x ′ 2 where y ′ and x ′ are coordinates of a point in a rotated and transalted coordinate system. The good news is that if you're willing to write a point ( x, y) as a vector v = [ x y 1], then the equation of a general parabola is just v t M v = 0 where M is the matrix 1 2 [ 2 d 0 0 0 0 1 0 1 0] WebThe process of obtaining the equation is similar, but it is more algebraically intensive. Given the focus (h,k) and the directrix y=mx+b, the equation for a parabola is (y - mx - b)^2 / (m^2 +1) = (x - h)^2 + (y - k)^2. Equivalently, you could put it in general form:
