Casio FXCP400 uTo determine the focus of the parabola x = 2(y – 1)2 –

Using G-Solve Menu Commands

When multiple solutions are obtained by a G-Solve command, only one solution is displayed at a time. For example, executing [Analysis] - [G-Solve] - [Focus] for an ellipse that has two foci will display only one focus at a time. In a case such as this, use the left and right cursor keys (or tap the left and right graph controller arrows) to cycle between the available solutions.

uTo determine the focus of the parabola x = 2(y – 1)2 – 2

1.On the Conics Editor window, input the conics equation and then tap ^ to graph it.

•Here, input the parabolic equation x = 2(y – 1)2 – 2.

2.Tap [Analysis] and then [G-Solve]. Next, on the submenu that appears, select the command you want. To determine the focus for this example, select [Focus].

•Press the left and right cursor keys to toggle the display between the two foci.

The following are examples for other G-Solve commands.
