My TI-83 plus will not display a normal quantile plot, when I press zoom 9 to generate the normal quantile plot I looks as if it's starting to display a graph but goes to err: syntax.

SOURCE: ERR: INVALID DIM displayed on graphing calculator

The solution for the problem is simple. When you use the calculator to create statistical graphs, it is configured to accommodate the specificities of the problem. However that configuration remains set after you terminate the problem. So when you try to use the calculator to do other problems it uses the stored configuration parameters, which may be incompatible with the new problem. In particular, list of paired-variables must have the same dimensions: There must be the same number of elements in each list.

To make a long story short, you should make it a habit to reset the Ram every time you want to do a new problem. If for reasons of you own you do not want to reset the Ram, you can prevent this type of errors from occurring. This is how you do it.

1. Press [2nd][Y=] (STATPLOT)
2. Choose option [4:PlotsOff][ENTER]. Screen displays Done
3. Press [2nd][0] (CATALOG)
4. Press [PGRM] (C) to jump to first command that starts with c.
5. Use arrow to scroll down to ClrAllLists, select it [ENTER]
   
6. Calculator displays Done
7. Start the new problem

To reset the Ram press [2nd][+] (MEM) [7:Reset][1:All Ram][2:Reset]. Press [CLEAR] to erase the Ram Cleared message.

Try zoom 6

Hello,
The calculator has two minus signs

1. The regular MINUS sign which is used with the subtraction operation. This operation is binary, requiring two operands (two terms). In a-b, a and be are the operands (they very specific names, but I will skip this detail).
   
2. The negation or change sign. This operation is called unary, requiring one operand. -a means take the negative of the number a.

These are the technicalities, in which you may not be interested. On calculators, the two operations are implemented differently, with two signs, the regular minus sign -- , and the change sign (-) usually smaller in size than the regular -- sign and raised above the main line.

Examples. Let (-) be the negation and -- the regular minus.

• If you enter (-) 12 the TI84Plus accepts it and calculates the negative of 12.
• If you enter 12 (-) 13 the TI protests with a syntax error
• If you enter 12 ( (-) 13) the calculator interprets it as 12* (-13) and calculates -156.
• If you enter --12, the calculator displays Ans--12, where Ans is the last result calculated. If Ans happens to be 0, the new result is obviously the one you are expecting. But if Ans holds a non zero value, this is incorrect.

Suppose you have to calculate X^(-2)*X^(-1/3)
You can enter it exactly as it is written above. In this case, you must use the change sign (-) in both factors.
You can also decide to use the power rules and enter the expression as X^( -2 --1/3). In this case the first minus is the negation and the second is the regular minus.

I could go on with a few more examples, but that will take us away from your present concern.

In short.

1. If the minus sign is the leftmost (first) symbol in your function (after the Y1=) you should use the negation. Any subsequent minus should be the regular minus --
2. If the minus sign is the first symbol in an exponent, you must use the negation. Any subsequent minus in the expression of an exponent should be the regular minus --

I hope it did not bore you death with details you do not care to know about. I do hope that it will help you prevent this type of syntax errors.

Prepare calculator to graph

Turn StatPlotsOff to avoid errors:
Press [2nd][STATPLOT][4:PlotsOff][ENTER].


Setup Graph type

• Press [MODE] key.
• In Mode set up screen, make sure that the angle unit is the degree.
• Use the arrows to move cursor to 3rd line to highlight {degree} and press [ENTER]
• On same screen, verify that Func is highlighted.
• 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)
  

Entering the functions to draw.

• 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.
  

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.
  

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
  

ZOOMING
You can also press [ZOOM] to adjust.



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

In the window screen you can set Xmin=-180, Xmax=180, Xscl=10, Ymin= -0.6, Ymax= 1.5, Yscl=1. The minus here is the change sign (-) to the right of the [.] dot.

You have to turn all statistical plots OFF before you draw function graphs. Press [2nd][Y=] to open the statistical plot configuration screen. Press [4:PlotsOFF] and then [ENTER]. When calculator answers DONE you are ready to draw function plots.
