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.
