Hello !
Examples :
<<Graphics`ImplicitPlot`
ImplicitPlot[x^2/4^2- y^2/8^2==1,{x,-15,15}];
Or :
<<Graphics`ImplicitPlot`
ImplicitPlot[x^2+3 x^2 y^3+67 x^4 y^2+34==0
,{x,-2,2},{y,-10,-5},ImageSize->200,PlotPoints->250];
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
