Best ResponseYou've already chosen the best response.2there is a general conic equation; something like x^2 + xy + y^2 + ... that i can never recall if its a standard conic (not twisted at an angle) you can recognize certain proerties

Best ResponseYou've already chosen the best response.2a parabola only has one square in it a circle will have the same constants for x^2 and y^2, and have a + in the middle an ellipse is like a circle, but it has different constants a hyperbola is like an ellipse, but with a minus sign

Best ResponseYou've already chosen the best response.2parabola: y = x^2 + .... circle: x^2 + y^2 = 8 ellipse: 4x^2 + 7y^2 = 15 hyperbola: 3x^2  2y^2 = 29

Best ResponseYou've already chosen the best response.2one is defined by geometric properties, while te other is defined by arithmetical properties. The two are equivalent, but its just the perspective studies that generated them.

Best ResponseYou've already chosen the best response.2y = 4 x^2 x^2 = 4  y (x  0)^2 = 4/4 (y  4) p = 1/4; and center (or vertex in this case) is at (0,4)
