SOURCE: WHen trying to graph anything, ERR: INVALID DIM

Hello,

The easiest and quickest way to start graphing is to reset the RAM. Press [2nd][MEM][7:Reset][1:All Ram][2:Reset], then [CLEAR] to clear the RAM Cleared Message and go to the main screen.

Hope it helps.

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

Hello,

The calculator has two minus signs

- 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).
- The negation or change sign. This operation is called unary, requiring one operand. -a means take the negative of the number a.

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.

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.

- 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 --
- 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 --

Seems unlikely that you get a syntax error for both graphing and Zooming. Probably the error is in the function you are trying to graph.

To reset the RAM,

Press [2nd]MEM][7:Reset][1:All Ram][2:Reset] [ENTER]

Calculator answers with Ram Cleared.

Press [CLEAR] button to erase the above message.

Once Ram is cleared, open the [Y=] function editor and at the Y1= line, enter [X,T, theta, n] key or [ALPHA][X], to draw the simple function Y1=X.

If that works, that means your calculator is OK.

Reset the calculator and restart your graphing.

Could you post the function you're trying to plot? Please give the exact sequence of keys you used to enter the function.

If I had to guess, I'd say you're using the "-" key when you should be using the "(-)" key.

Simply press the (-) key before entering a negative number, in the same place you see the negative sign in print.

For example, to multiply 3 by -4, press 3 x (-) 4 ENTER

Try rewriting your equations in the equivalent forms that follow.

Y1=3-X

Y2=(1-X)/3

If you do not get a syntax error it means that you were not using the correct minus sign.

If the - is the first symbol after the equal sign you must use negation (-) or change sign key.

Similarly, after the division / key you must use the negation or change sign (-)

Y1=3-X

Y2=(1-X)/3

Press the 2nd Button then the ZOOM button. Make sure that AxesOn is highlighted. If not, move your cursor down until you on AxesOn and press ENTER.

If AxesOn is highlighted, then it is probably your window. Press ZOOM, then 6.

You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

Ok i had the same problem- If i remember correctly my "window" was messed up. Check it out... If not i always pull the "take batteries out while on" trick which resets the ram.
