Unformatted text preview: responding directrix defines a conic section (plural: foci). TI-83 Plus Conic Graphing Page 46 Term Definition Hyperbola A plane curve generated by a point so moving that the difference of the distances from two fixed points is a constant. Major axis The axis passing through the foci of an ellipse. Minor axis The chord of an ellipse passing through the center and perpendicular to the major axis. Parabola A plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line (directrix). Semi-major axis One half of the major axis of an ellipse (as that formed by the orbit of a planet). Semi-minor axis One half of the minor axis of an ellipse (as that formed by the orbit of a planet). Slope The tangent of the angle made by a straight line with the x-axis. Vertex A point where an axis of a circle, ellipse, parabola, or hyperbola intersects the curve itself.

TI-83 Plus Conic Graphing Page 48 Error Recovery Instructions Conic Graphing Application Errors If the curve does not display or a partial curve displays after you press V, the parameters you entered may be outside of the acceptable range for the calculator. All Equations If this error occurs or if you receive this error message… Make this change: The curve does not display correctly, or a partial curve displays. The parameters you entered may be outside of the acceptable range for the calculator. If you changed the CONIC SETTINGS window settings mode to MAN, press T and select Zoom Conic to redefine the window settings. Window range error or zoom error Change the window parameters (Xmin, Xmax, Ymin, Ymax) so that the window is larger or smaller, depending on the graph. Invalid input Change the input to a valid value. TI-83 Plus Conic Graphing Page 49 If this error occurs or if you receive this error message… Make this change: Requested zoom has invalid results Change the window parameters (Xmin, Xmax, Ymin, Ymax) or Xfact and Yfact zoom factors. You must exit Conic Graphing to change the Xfact and Yfact zoom factors. Invalid AppVar CONICSD. Please remove. The application variable (AppVar) named CONICSD has been corrupted, or another application variable uses the same name. Delete the AppVar, or use TIGRAPH LINK to remove it and save it on your computer. Error saving Conics settings The AppVar CONICSD cannot be modified. Delete the AppVar, or use TIGRAPH LINK to remove it and save it on your computer. TI-83 Plus Conic Graphing Page 50 Parabolas If you receive this error message… Allowed parameter values: A e 0 Allowed parameter values: p e 0 Make this change: Change the parameter so that A < 0 or A > 0. Change the parameter so that p < 0 or...
