4-2-2 Inputting Equations
u To input an equation using a Conics Form
Example: To use a Conics Form to input the equation for a parabola with a horizontal axis (principal axis parallel with x-axis) (1) On the application menu, tap C to start the Conics application. (2) On the Conics Editor window, tap q, or tap [Form] and then [Insert Conics Form]. · This displays the Select Conics Form dialog box.
(3) Select the Conics Form of the type of equation you want to graph, and then tap [OK]. · Since we want to graph a parabola with a horizontal axis in this example, select "X = A(Y K)2 + H". Tap [OK] to close the Select Conics Form dialog box, and display the selected equation in the Conics Editor window.
(4) Modify the equation on the Conics Editor window as required. · Here, we will change the coefficients of the equation as follows: A = 2, K = 1, H = 2.
(5) Tap ^ to graph the equation.

Inputting an Equation Manually
To input an equation manually, make the Conics Editor window active, and then use the soft keyboard for input.
Input the equation here. Conics Editor window
Transforming a Manually Input Equation to a Conics Form
After you manually input an equation on the Conics Editor window, you can use the procedure below to transform it to a preset Conics Form. Example: To transform the equation x = Ay2 + By + C (x 1)2 x2 to the standard Conics Form + (y 2)2 = 2 2 4
u ClassPad Operation
(1) On the Conics Editor window, input the above equation.
Hint: Tap the ) tab of the soft keyboard. The 2D fraction and 2D exponent are very helpful in entering this equation!
(2) After inputting the equation, tap w or tap [Fit] and then [Fit into Conics Form]. · This transforms the equation so it becomes x = 2y2 8y + 17 . 2
Tip
· If the equation you input cannot be transformed into the standard Conics Form you selected, the message "Can't Transform into This Type" appears. A2 B2 2 2 (x 1) _ (y 2) Example: To draw the hyperbola with a horizontal axis =1 22 32 The standard form of a hyperbola with a horizontal axis is:

Drawing a General Conics
Using the conics general equation Ax2 + Bxy + Cy2 + Dx + Ey + F = 0, you can draw a parabola or hyperbola whose principal axis is not parallel either to the x-axis or the y-axis, a slanted ellipse, etc. Example: To draw x2 + 4xy + y2 6x + 6y + 4 = 0
u ClassPad Operation
(1) On the Conics Editor window, tap q, or tap [Form] and then [Insert Conics Form]. (2) Select "AX2 + BXY + CY2 + DX + EY + F = 0" and then tap [OK]. · This closes the Select Conics Form dialog box, and displays the selected equation in the Conics Editor window. (3) Change the coefficients of the equation as follows: A = 1, B = 4, C = 1, D = 6, E = 6, F = 4. [. . . ] Ambient temperature range: 0°C to 40°C Dimensions: 21 mm (H) × 84 mm (W) × 189. 5 mm (D)
