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: x^2 + 2mxy + m^2 y^2 -2 [h (m^2 - 1) +mb]x -2 [k (m^2 + 1)^2 -b]y + (h^2 + k^2 ...

WebTo convert from rectangular to polar: r^2=x^2+y^2. tan theta= y/x. This is where these equations come from: Basically, if you are given an (r,theta) -a polar coordinate- , you can plug your r and theta into your equation for x=rcos theta and y=rsin theta to get your (x,y). The same holds true for if you are given an (x,y) -a rectangular ... lil suzy ethnicity
