Curves from intersection of plane and cone
Parallel to curved face of cone
y2=kxy^2 = kxy2=kx or y2=4axy^2 = 4axy2=4ax
x2a2+y2b2=1\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1a2x2+b2y2=1
x=±ax = \pm ax=±a and y=±by = \pm by=±b
x2a2−y2b2=1\frac{x^2}{a^2} - \frac{y^2}{b^2} = 1a2x2−b2y2=1
y=±baxy = \pm \frac{b}{a}xy=±abx
xy=c2xy = c^2xy=c2
(x1,y1)(x_1, y_1)(x1,y1)
Swap xxx and yyy in equation
