How do i graph an equation on a ti-84 plus silver edition calculator?


1. To graph a function, Press [Y=] to enter the function editor.
2. Type in a legitimate function.
3. Press ENTER to validate the function.
4. Press the GRAPH key to draw the graph.
5. Play with the window dimensions or use the ZOOM feature
to see more of the graph (or less).


Try your settings by drawing the function y= x
If you have problem with Invalid Dimension or other errors, turn the
Statistical Plots OFF.
To do so, press [SHIFT] [Y=] to open the Stat Plots.
Type in the number to the left of the Option PlotsOff. Then press ENTER.

I need to enter 4.5+t=3.1 how do i enter this into my calculater


You always want to have every number on one side of the equation so that you can have it in the form y = something.
So, this
4.5 + t = 3.1
should become
4.5 + t - 3.1 = 0
or
1.4 + t = 0
Now you can enter this into your calculator as
Y1 = x + 1.4
Press the GRAPH button and you should see the graph of your function. You might have to adjust the window size, etc., using the WINDOW or ZOOM buttons.

How do i graph?


The fact that you are asking how to graph makes believe that you solved the problem about 'invalid dimension' . I am glad that worked for you.

This
should help you setup your calculator to do graphing.

1. Prepare calculator for graphing
Turn StatPlotsOff to avoid errors:

Press [2nd][STATPLOT][4:PlotsOff][ENTER].

2. Setup Graph type
  • Press [MODE] key.
  • In Mode set up screen, make set the angle unit (if you are drawing trigonometric functions)..
  • Use the arrows to move cursor to 3rd line to highlight degree or radian and press [ENTER]. The important thing is that you be aware of the unit so that you do not get unexpected results.
  • On same screen, verify that Func is highlighted. If you are drawing PARametric plots, POLar plots or SEQuence plots, you highlight the relevant item in the list
  • If it is not, use arrow to highlight Func and press [ENTER] to validate.
  • Do not worry if you do not have exactly the same screen as in the screen picture (We may have different OS Versions)

3. Entering the functions to draw (assuming you want to draw y= functions)
  • Press [Y=] to enter function editor.
  • Type in a function
  • Press [ENTER] at the end of each function.
  • Before pressing [GRAPH], make sure that all the = signs that define the functions to be graphed are highlighted white on black. If one is not highlighted, use arrow to move cursor on the sign and press [ENTER].
  • In the screen capture 4 functions are slated to be drawn.

4. Selecting the Graph Style (You may ignore this now, because it is unimportant for just one graph)
  • Select the graph style: The small piece of line to the left of a Y that defines a function is the style.
  • Move cursor on it and press [ENTER] .
  • Each [ENTER] (on same line) selects another style.
  • On the next screen you have all the styles available on the calculator.
  • Do not select the bubble on line 6: It is for animations. It will not leave a trace at the end of the plot.

5. Drawing the Graphs
  • Press [GRAPH] to see the graphs.
  • If one of them is missing, verify that its = is still highlighted, then use the [WINDOW] to set the Window dimensions,
  • Here are the dimensions of the standard window

6. ZOOMING
You can also press [ZOOM] to adjust.

The selection 6:ZStandard sets the dimensions as on the screen Titled Window (above).

When I'm entering a quadratic function, I'm getting the graph of something that is not a parabola like it should be. However, when I graph x^2 by itself, it looks the way it should. What can I do to fix...


The actual graph depends on the constants (parameters) that are in the equation. Try playing with the dimensions of the window by zooming in or zooming out.
The most interesting part of the graph is the region near the maximum or minimum.
Here is a graph of the function y=X^2-5X 13 when drawn with standard window dimensions
3b585d8.jpg
Not very revealing. However if you press the Zoom key and select [2:ZoomIn] you see this (no changes) but the calculator is ready to accept your input concerning the new center of the graph.
bcd4c3e.jpg
At this stage, use the Arrow keys to move the center of the graph to another point as in the next screen capture.

0e09736.jpg
Notice the new center as a sign on the screen and its coordinates at the bottom. By pressing [ENTER] you get this
fc695b8.jpg
If you keep Zooming in you may end up having something that does not look like a parabola anymore.

To summarize: Use the Zoom In or Zoom Out functions or find where the minimum/maximum is, center the graph on that point and modify the windows dimensions (Xmin, Xmax, Ymin, and Ymax) so as to get as much of the interesting part of the graph as possible.

How do i fix the window numbers on my calculator


You can try to reset the calculator: In so doing the default configuration is restored. If that works for your graphs why fiddle with the setting?
Ok to reset calculator (do not worry I will tell you how to change window dimension):
Press [2nd][+] to access the (MEM)ory management.
Press [7:Reset][2:Defaults] [2:Reset]
The window dimension will be restored.

To change dimensions
In main calculator screen press the [WINDOW] function key
Enter the value of Xmin. If negative use the change sign key (-) under key 3
Enter Xmax value. Make sure that Xmin is less than Xmax.
Leave the Xscale at 1
Enter Ymin. If negative use the change (-) key
You can leave the Yscale at 1, Xres at 1.
You can change the DeltaX but if you take too small a value your graphs will take long to be drawn.

If you ever get a problem, just press the [ZOOM] function key and select [6:ZStandard] it will restore the default dimensions.

Graph feature not working on my TI-83 Plus


Simple:

Hit this sequence:

"ZOOM" "0"

That is for the "Zoom Fit" option. The calculator does not like the window you have for the equation you've given it. With this option, it will automatically give you the best fit in the window for the equation!
