Question about Texas Instruments TI-89 Calculator

Hello,

It is actually quite simple. The calculator can perform severa types of graphing, but the most common is the drawing of functions defined by a relation of the form y= fonction(x), or y=f(x) for short.

The procedure is described for the TI 89 Titanium. It is valid for the TI 89 except if I enter the color of a key.

1. Before you start, you should set up the calculator to begin a New Problem. The command for that is accessed through the menus.

Press the [HOME] key to go to main calculator folder.

In Home folder, press [2nd][F1] to access [F6][2:NewProb]. Press [ENTER] to execute the command. Screen should display Done.

2. Press yellow [Diamond] key (it is the equivalent of the CTRL key in computers) then [F1] to open the [Y=] editor.

3. Use the keypad to enter your first function on Y1= line. Press [ENTER] when finished with Y1. This will select the curve to be drawn, and a check mark appears to the left of the Y, in Y1=. If there is no check mark, the curve will not be drawn. If that happens, move cursor on Y1= and highlight it and press ENTER.

4. Enter the next function. Press [ENTER] when finished.

Try the functions Y1=3*x+0.5 and Y2=x^2 -1.

5. Press the yellow [Diamond] key to access [GRAPH]. The cartesian screen appears, the calculator starts graphing. While graphs are being drawn, the indicator BUSY is displayed at the bottom of the screen, on the right.

Here is what your screen looks like.

6. If BUSY indicator disappears, graphs are finished. If nothing is displayed on the screen except the axes, the functions may be out of range. In that case you can adjust the window dimensions.

You can change the values of Xmin, Xmax, Ymin, Ymax, or press [F2:Zoom] to use any of the zooming options.

This is the basic procedure to draw y=f(x) graphs.

Hope it helps.

Look for a key labeled Y= ( the y= editor) and press it. Use the key pad to type in the right side of the function.

Press Graph to display the graph.

If drawing is out of range set the window parameters. Alternatively (if there is a zoom key) use it to select a ZoomIn, a ZoomOut , Zoom Standard.

Press the GRAPH key (the rightmost of the function keys at the very top of the keyboard). You can then use the WINDOW and ZOOM keys to look at different parts of the graph.

Press Y= (the first function key on the top row). On the line beginning Y1=, put in the right hand side of the equation: 3 ALPHA [X] - 1

Press GRAPH (the last function key on the top row) and you'll see the graph. If you want to look at different parts of the graph, press WINDOW and change the window settings.

Turn calculator [ON]. If you do not see the menu icons, press [MENU]. Use the arrow keys to highlight the [GRAPH] icon.

An entry screen appears where you enter the functions you want to graph.

On the first line you have Y1= . After the equal sign enter 2[x] [X, theta,T] + 1. When finished press [F6: Draw] Your graph appears on the screen. If you see the axes, but no graph, press [Shift][V-Window] and press [F3:Std] then [SHIFT][QUIT] will take you back to the screen where you enter the functions to draw. There press [F6:Draw].

Hope it helps.

Put the calculator in radian mode and it will graph trig functions just fine. If you don't know how to change it to radians, then go to mode and cursor over to select radians. I am assuming you know where the sine, cosine, tangent, etc. keys are.
