Hello !

Examples :

ImplicitPlot[x^2/4^2- y^2/8^2==1,{x,-15,15}];

Or :

ImplicitPlot[x^2+3 x^2 y^3+67 x^4 y^2+34==0

If you specify also {y,-10,-5} (a vertical zone) , you will be able to see the graph of a implicit-curve wich cannot be explicited!
But it is not necessary with polynomial functions...

Objet : [mg57287] plot hyperbola

  HI, i am a beginner. Will u please tell me how to plot
hyperbola,parabola,ellipse and circle in their standard forms
   x^2/a^2 + y^2/b^2 = 1
  x^2/a^2 -- y^2/b^2 ==1 etc.
 Also how do you plot a general curve (y versus x), say
    x^2 +3 x^2 y^3 +67 x^4 y^2 +34==0
 *without solving explicitly for y* ( or x)
  Please help
