    Circle, ellipse, hyperbola, parabola are examples of conics Conics usually have an equation of degree 2... There are many forms of equation but right now just stick to the most basic one

    parabola: Ax2 + Dx + Ey = 0 circle: x2 + y2 + Dx + Ey + F = 0 ellipse: Ax2 + Cy2 + Dx + Ey + F = 0 hyperbola: Ax2 – Cy2 + Dx + Ey + F = 0

    what is the purpose of getting the asymptotes of the hyperbola?

    #Jedai17 provided you the general form of the conics.. The standard forms are these.. Circles : x^2 + y^2 = r (r is the radius) Ellipse: x^2/a^2+ y^2/b^2 = 1 for horizontal axis and x^2/b^2+y^2/ a^2 = 1 for vertical axis (a is one of the co-ordinate of major axis and b a co-ordinate of minor axis) Parabola: y = x^2

    Btw general form are little advanced formulas to deal with Ill say keep it simple!! :)

    Hey @robinfr93 , slight mistake in there... *Circles* x^2 + y^2 = r^2 ... in place of *r*...

    hahahhaa!! yes you do!! @saloniiigupta95 thanx for the answer back there, I for got to square two there so was getting the wrong answer!! yeah ryt!! Thanx for pointing that out!! Another Typo!! Sigh!! :P well I'll say if you don't have a solid foundation in graphing functions and asymptotes and all, try reading Precalculus by John W Coburn. It'll Clear all your doubts adn will give you an understanding on how to use all these stuff in rela life!!

    The "general" equation of a circle is: x2 + y2 + Dx + Ey + F = 0 The "center-radius" form of the equation is: (x – h)2 + (y – k)2 = r2 another information about circle. @saloniiigupta95 your equation in circle is correct

    nah I'm pretty sure thats also standard equation. general equation of a circle is of the form ax^2 + by^2 + hxy + 2gx + 2fy + c =o
