Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator

Ad

There is no vertical (or otherwise) asymptote feature on a TI84PLUS. It
seems to you that the calculator is drawing the asymptote. However
when you plot a CONNECTED Graph a line is drawn from one point to the
next: The last point on one side of the asymptote is thus connected to
the first point on the other side, effectively mimicking the drawing of
the asymptote.

To get rid of this spurious effect, **draw dotted graphs**,
but you will see fewer points, because the points are drawn at constant
intervals in X. This is set by the Xres variable, in the Window
configuration screen.

Here is a function that will "show" you a vertical asymptote on the
TI84PLus, when graph is drawn connected, but on a calculator with a
higher resolution, you see none. A calculator cannot handle infinity.
You can with the help of your mind's sight, so to speak, see the
asymptote on the graph.

First you must use a graphing calculator.

Most graphing calculators graph functions, i.e. relations of the form y=f(x).

Some graphing calculators are able to graph equations (not necessarily functions). On one of these calculators your draw the vertical line x=-3, then you shade to the left of the point x=-3. That gives you the real line from infinity up to but not including x=-3.

Generally, people do not need calculators to find the solutions to inequalities in just one variable.

On the x-axis (horizontal axis) represent the time variable. On the y-axis (vertical axis) represent the temperature.

Curves drawn with the help of a graphing calculator are no mere sketches, they are a lot more accurate than a human hand will be able to draw.

Unfortunately for you, the calculator you are using is no graphing calculator and thus cannot draw. However, it is able to generate a table of values which you might use to sketch curve on a sheet of graph paper.

The asymptote you see is in truth a spurious effect. It appears when you draw connected graphs. There is no command that turns that "non-existing feature" ON and OFF.

If you do not want to see the "asymptote" draw dotted graphs. The drawback is that you will have fewer points near the asymptote because the curve grows too fast. If you decrease the x-step to have more points, the graph will take longer and you may run out of RAM.

I am not sure how you can create such function (the range limitation do not work for x=c) but you can draw a vertical segment, just do not call it a function.

Draw a graph Y1=0

Then press SKETCH function key and use the F6 key to cycle through the TABS at the bottom of the screen. Look for the TAB named PEN. and click the function key below it.

Use the arrows to move the cursor to a spot on the screen (near the bottom), Press EXE to fix the starting point of the segment. Then use the Up arrow to draw a vertical segment from bottom to top.

If you just want to draw figures (not graphs) on the calculator you should use the [Draw] command.

Press [2nd] [PRGM] (DRAW)

Select [4:Vertical]

Command echoes on main screen as Vertical

Enter the x-value where you want the line drawn (ex: 2) and press ENTER

You will get a vertical line at x=2.

Press [2nd] [PRGM] (DRAW)

Select [4:Vertical]

Command echoes on main screen as Vertical

Enter the x-value where you want the line drawn (ex: 2) and press ENTER

You will get a vertical line at x=2.

I am enclosing a link to a web page that gives you the definition of the domain of a function and its range. You should read it to correct the confusion you entertain between domain and range.

In what follows I will speak of X and Y values.

Let me restate what I think you wanted to do. Ignore my rambling if you do not recognize your intention.

You want to draw the sin(X) function for X varying from Xmin= -2*pi radians to Xmax=2*pi radians. However, it you do not specify the Ymin and Ymax values for the vertical window dimensions a big portion of the screen is not used (vertically) and you want the height of the curve to take most of the screen. Specifically you want to set the vertical height of the window to go from Ymin=-1 to Ymax=1.

Press [SHIFT] [F3:V-Window] to set window dimensions.

On line Xmin= type : (-)2*[SHIFT][EXP] (Pi); or just (-) 6.3

Press [EXE] to validate the choice

On line Xmax= type 2*[SHIFT][EXP] (Pi) or just 6.3

Use down arrow to highlight the line Ymin= and enter (-)1

On line Ymax= type 1

You may or may not want to change the X(scale) and the Y(scale)

Press [EXIT] to exit the window settings.

Draw your graph.It will occupy all the screen.

Here is what you will get.

Hello,

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.

hey faymalaka

what's up. ok so you can't do what you want to do. It just can't be done. I'm pretty sure it can be done on a casio. however, you can do it just not by graphing. (this is on your TI) ok so first go to 2nd ZOOM and turon off the Axes and the Expr. Then Go to 2nd Prgm. Then go to A or Pen. and you can draw. as long as you first go to pen then you can draw lines and circles and stuff like that. but you must first go to draw then pen. then a suggestion i would save it by hitting 2nd prgm then going right to STO. this allows you to save your drawins as like 1 or 2 or so one. and then if you want to start over from your last picture because you made a mistake just clrdraw and then start over by recalling it. THis is under the store function. by the way the pen turns on and off with the enter button. GOOD luck if you don't get it feel free to ask questions.
