Conics Formulas – HSC Math

Posted In: Mathematics

In mathematics, a conic section (or simply conic) is a curve obtained as the intersection of the surface of a cone with a plane. The three types of conic section are the hyperbola, the parabola, and the ellipse.

  1. Identification of conics from general formula: $ax^2+by^2+2gx+2fy+2hxy+c=0$
    $i. ab-h^2=0, Parabola$
    $ii. ab-h^2>0, Ellipse$
    $ii. ab-h^2<0, Hyperbola$
    $iv. a=b,h=0, Circle$
