kHow to draw a simple graph (3)

Description

Use the following procedure to graph the function of a parabola, circle, ellipse, or hyperbola.

Set Up

1. From the Main Menu, enter the CONICS mode.

Execution

2. Use the cursor fc keys to specify one of the function type as follows.

Graph Type

 

Function

Parabola

X = A (Y – K)2 + H

 

X = AY2 + BY + C

 

Y = A (X – H)2 + K

 

Y = AX2 + BX + C

 

 

Circle

(X – H)2 + (Y – K)2 = R2

 

AX2 + AY2 + BX + CY + D = 0

 

 

 

Ellipse

(X – H)2

(Y – K)2

 

–––––––– + –––––––– = 1

 

A2

B2

Hyperbola

(X – H)2

(Y – K)2

 

–––––––– – –––––––– = 1

 

A2

B2

 

(Y – K)2

(X – H)2

 

–––––––– – –––––––– = 1

 

A2

B2

3.Input values for the required variables.

4.Graph the function.
