Graphing an ellipse on TI-nspire CX CAS

Question

How do I graph an ellipse on a TI-nspire CX CAS?

I know how to graph an ellipse with the equation $$\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2 }=1$$

but I don't know how to put coefficients in the equation on the calculator. For example, how do I graph the ellipse with equation $$x^2 + 2y^2 = 1$$

Answer 1

Go the graph screen, then press the menu button. Press 2:Equation, then 4:Ellipse.

Edit: Set the denominators to 1, and h and k to 0.

Answer 2

Go the graph screen, then press the menu button. Press 2:Equation, then 6:Conic.

It will allow you to enter the coefficients of the terms.

Answer 3

So with the new software update, lots of things have changed. Turn on calculator. Hit B to go to graph. Hit menu, 3,2 to go to relation. Type in equation $$(x−h)^2/a^2+(y−k)^2/b^2=1$$ as shown above.
