A [i]quadric surface[/i] is the graph in space of a second-degree equation in [i][math]x[/math][/i], [i][math]y[/math][/i], and [i][math]z[/math][/i]. The quadric surfaces in this interactive figure are all graphs of equations of the form [math]Ax^2+By^2+Cz^2+Dz=E[/math].[br][br]As you slide the sliders to change the parameter values, pay attention to how different parameters impact the shape of the surface.
