All Equations

Error Message

Description

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 q 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.

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 TI Connect™ CE Software to remove it and save it on your computer.

Error saving Conics settings.

The AppVar CONICSD cannot be modified.

Delete the AppVar, or use TI Connect™ CE Software to remove it and save it on your computer.

Circles

Error Message

Description

Allowed parameter values: R ≥ 0.

Change the parameter so that R ≥ 0.

Allowed parameter values: A ≥ 0.

Change the parameter so that 0 < A < 1E50.

Allowed parameter values: 0 < e < 1.

Change the parameter so that e > 0 and e < 1.

Allowed parameter values: p ≠ 0.

Change the parameter so that p < 0 or p > 0.

Hyperbolas

Error Message

Description

Values out of range for computation. Recheck window settings.

If the calculator is in FUNC or PAR mode, change the parameters so that

If the calculator is in POL mode, change the e or p parameter so that e2 or ep < 1E100.

Allowed parameter values: A > 0.

Change the parameter so that A > 0.

Allowed parameter values: B > 0.

Change the parameter so that B > 0.

Allowed parameter values: e > 1.

Change the parameter so that e > 1.

Allowed parameter values: p ≠ 0.

Change the parameter so that p < 0 or p > 0.

Window range error or zoom error.

Change the window characteristics or change P so that the values involved in the calculation do not exceed the calculator’s limitations.

Parabolas

Error Message

Description

Allowed parameter values: A ≠ 0.

Change the parameter so that A < 0 or A > 0.

Allowed parameter values: p ≠ 0.

Change the parameter so that p < 0 or p > 0.

Window range error or zoom error.

Change the window parameters (Xmin, Xmax, Ymin, Ymax) and/or the p value.

Values out of range for computation. Recheck window settings.

Change the window parameters (Xmin, Xmax, Ymin, Ymax) and/or the p value.
