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
