SOURCE: Plotting Points

you can reset all variables, without losing all your programs. you can hit 2nd>Mem(plus symbol)>reset>All ram Then verify that you wish to do so... It should reset to a working condition... If it doesn't then you may need to lose your programs in order to get your calc to a working condition.

SOURCE: when i try to graph a scatter plot on my ti-83

Your stat plots are on, and may not be filled out/ correctly filled out.
go to [Y=] and go up to the stat plots ([Plot 1], [Plot 2], [Plot 3] ) and turn off the ones that are "ON" ( highlighed black w/ white text.) and press [ENTER] on the ones that are on and the problem is no more.

SOURCE: I can't graph on my ti-84 plus silv. edition

More than likely, you've put in a number in the xmin or xmax that is not correct. Example....you put in an xmin of 10 and an xmax of -10 which would be backwards. This could also happen in the ymin or y max.

The easiest way to fix this is to press zoom 6 which wil get you back to the default graph of xmin of -10, xmax of 10 and ymin of -10 and y max of 10.

If you can't see your graph on this screen and need to change the window, just be sure the number in the min for both x & y is smaller than the number in the max. You change your window size by pressing the window button.

Hello,
Some old configuration settings, or old variables are spoiling your fun. Clear the RAM and start again.
Hope it helps.

SOURCE: err:syntax when I try to graph with ''-''

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.

I can't see all of plotted points in scatter plot


Try to set the Zoom window to ZoomStat, this way the scatter plot will display all statistical points in the data set.

Why can't i see the plotted points when i try to graph my L1 in a scatter-plot?


You cannot have a scatter plot with just one variable. You need values in L1 and values in L2. If you have only one set of values you can do 1-var statistics and plot a histogram (x-value vs. frequency).

Fix the ERR:INVALID DIM message on my TI-84 plus, please.


INVALID DIM error message may occur if you are trying to graph a function that does not involve the stat plot features. The error can be corrected by turning off the stat plots. To turn the stat plots off, press 2nd, STAT PLOT , and
then select 4:PlotsOff.

I am trying to graph a least-squares line on my TI-84 Plus. I have the numbers correctly plugged into my Stat Edit tables, and I am able to access my linear equation, and the first time I entered my graph...


After you enter the data draw the SCATTER plot first.
When you perform the (linear) regression analysis LineReg, save the regression equation to a function, for example Y1
The syntax is
LineReg L1, L2, Y1 ENTER


From the Stat>CALC menu press LineReg
The command echoes on command line
Press [2nd][1] to enter the L1 list on command line
Press [,] to separate
Press [2nd] [2] to enter L2 on the command line
Press [,] the comma again
Press [VARS][>][Y-Vars][1~Function][1:Y1] [ENTER]
Press [GRAPH] to have the regression line equation drawn
on the same screen as the Scatter Plot you drew before.

Graphing problem


hit 2nd y= and edit your stat plot to make sure you have the right stat plots turned on or just make sure that there is an x and y for EVERY value of your stat plots
