Conics Function

Graphing a Conic:

In the Main Menu, press 9 for Conics. The first screen you come to will be a

choice of conic equations already input into the calculator memory. Choose one

by arrowing and highlighting the chosen equation and press EXE. Then enter

the values in for the variables in the equation as listed. After each value entered,

press EXE to store and move to the next value. Press F6(DRAW) to see the graph

of the conic equation. Note, the graph of a circle may not necessarily show up as

a circle because the view window needs to be set manually (Choose a X-value that

is twice as large as the Y-value to get a perfect circle).

Equation Function

Solving Systems of Equations:

To solve for a system of equations, select the equation function by pressing the

XT button. Choose F1 for Simultaneous equations. Choose the number of

unknowns you have by pressing the corresponding function key. Enter in the

values for each of variables in the equations. After the values are entered in, press

F1(SOLV). The calculator will solve for the unknown values. REPT at the

bottom of the screen will take you back to the previous screen.

Solving for a Variable in Polynomials:

You can solve for a variable in polynomials up to the third degree. Press F2 for

Polynomial when you enter the equation function. The calculator will ask you to

specify the degree of the polynomial by pressing either F1 for 2 or F2 for 3. Enter

in the values for the polynomial in the matrix shown and then press F1(SOLV).

The two values for X will show up in a matrix.

Solving Equations:

Enter into the equation solver by pressing F3 for

Solver. To enter the equation

in question, you may enter numbers, alpha-characters, and symbols. If you do

not put an equals sign in the equation the calculator will assume that the

equation is to the left of the equals sign and that a zero follows it. To specify a

letter or number other than zero, type SHIFT, = and then type the value. After

the equation is entered, press EXE to store. The variables in the equation will
