If you upgraded the Operating System to the 2.53 MP version or if your calculator was shipped with that version (the lastest) that is how the new OS works. It tries to imitate what you would see on a textbook. The exponents are raised above the main line and that requires more vertical space.

It is your friend who should be jealous not you.

But if that bothers you, well there is something you can do about it. Configure the calculator to use the classic (OLD) view.

  1. Press the [MODE] button.
  2. Use the Down Arrow key to move cursor to next page of options.
  3. On first line of new page, use the Right Arrow key to highlight CLASSIC and press ENTER.
  4. Press [2nd][MODE] to (QUIT)
  5. Press [Y=] to open function editor.
  6. Enter a function with an exponent (any exponent)
Warning: If you deactivate the MathPrint you will lose some functionalities (especially fraction manipulations).

How to graph a function
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.

When using zoom how can you extend the square root sign over a equation?


I admit that I do not quite understand what you want to do. The Zoom function allows the user to Zoom In ( see a smaller part of the graph in more detail ) or Zoom Out (to view more of the graph in less details) That applies to any graph that is displayed
As to the square root function, if you enclose the argument (expression) in parentheses making sure that you close the right one ) , everything inside the () will be part of the argument.

How to set up mode for graphing


To draw a graph, it helps if you know approximately where it is going to show up so that you can set up a window.
Try this:
Press the [Y=] button
Enter the following equation: 5*x^2-5*x (five x-squared minus five times x) by pressing the following calculator keys:
5 X (times) x^2 (x squared key) - (minus) 5 X (times) x (key labled x,t,n) in between the ALPHA and STAT keys
now press the zoom key and select #6 - ZStandard (this will give you a standard zoom)
You should see a parabola drawn on the screen.
If you enter in some equation and do not see it on the screen, you can try zooming out (zoom key) or setting up your display window, using the window key.
This is where it helps to know where your x and / or y intercepts are.
From there, you can use trace to move around the graph, 2nd+graph (table) to see your x and y intercepts.

I cant highlight both equations in Y= to graph


Hello,

First thing to do before any new type of problem
1. Turn StatPlots OFF : press [2nd][STATPLOT][4:PlotsOff] [ENTER]

Second thing: Clear the statistical lists
2. Press [2nd][0][PGRM] DownArrow to point to ClrAllLists.
3.Press [ENTER][ENTER]

Third thing : Configure the graph type to be FUNCTION graph
4. Press [MODE]. If FUNC (on fourth line) is highlighted. Press [Y=] and start entering the functions.
5. If FUNC is not highlighted, use Down arrow till 4th line, highlight FUNC and press [ENTER]. Press Press [Y=] and start entering the functions.

Fourth thing: Enter function and select them for graphing
1. As you start entering the function Y1=, notice that the = sign becomes highlighted. Press [ENTER] when Y1 is typed in. Make sure the = sign for Y1 remains highlighted as cursor moves to Y2=.
2. Keep entering the functions and verifying that their = signs remain highlighted as cursor moves to another equation.
3. When finished press [ENTER]
4. Look at the graph style for each function: it is a bit of line to the left of each Y. Here is a picture of all the 7 styles.

5d53e23.jpg

To set a graph style, highlight the style to the left of the Y, and press [ENTER]. Each time you press [ENTER] you see a new style, in the order shown on picture.
Avoid the style of Y6, it is bubble, and as such will burst and disappear once graph is finished. Avoid also the triangular ones (for Y3 and Y4) they will shade areas of the graph, and may hide other functions.

Fifth thing: Graph Functions.
1. You can press [GRAPH] to see your graphs.
2. If one curve is missing (and you have not set its style to be rhe bubble), it may be due to the Window dimensions.

Sixth Thing: Set Window dimensions and Zoom.
1. Press [ZOOM][6:ZStandard] to use standard window dimensions.
2. If curve still missing, Press [ZOOM][3:Zoom Out] to zoom out so that you may be able to see a bigger range for the functions.
3. If necessary press [WINDOW] and set the Xmin, Xmax, Ymin,Ymax to values of your own.

d44f2dd.jpg

Dimensions must obey the conditions: Xmin < Xmax, and Ymin < Ymax.

Hope that helps.

How to graph an equation on a t1-83?


how to fix window to graph Pythagorean property

Sep 01, 2009 | Texas Instruments TI-83 Plus Calculator

1 Answer

The calculator is only graphing a half circle when it should be a full circle, specifically not in the negative y-values of the plane.


A circle is not a function and cannot be graphed in the regular y=screen. You can graph a circle in parametric mode.

To graph a circle in the regular y= screen, you have to graph it in 2 lines on the y= screen. I assume you've solved for y and gotten a square root equation. Remember a square root can be positive or negative. In line 1 of y= screen graph what you've been graphing and then graph the same equation in line 2 but with a negative in front of the equation. You'll get something that looks like an oval since the calculator screen is rectanglular. To make it look more circular (both parts aren't going to connect), press zoom and then select #5 (square).
