Err syntax pops up when trying to graph


You have a syntax error in the function you're trying to graph. Could you post the function in question?

Everytime I try to do powers and square roots I get an error message


An ERR: MEMORY is given when there is not enough memory to perform the instruction or function. To increase available memory by deleting the contents of any variable (real or complex number, list, matrix, Y= variable, program, Apps, AppVars, picture, graph database, or string), follow these steps. • Press [2nd] [MEM] to display the MEMORY menu.
• Press 2: Mem Mgmt/Del.
• Select a variable or data that needs to be deleted and press [ENTER].
• Use the arrow keys to move the cursor next to the item, and then press [DEL]. The variable or data should now be deleted from the memory.
When deleting programs or Apps, a message asking for confirmation will appear. Select 2:Yes to continue. To leave any variable screen without deleting anything, press [2nd] [MODE].

SYNTAX ERROR


I am willing to bet that if the calculator could talk she would tell you to stop feeding it commands that make no sense. Joking aside, each command has a certain syntax, similar to sentences you make in English: a prescribed order of the components of the sentence.

For some calculators (the older generations) you press a number then the square root key to get the square root. For the newer ones, you press the square root key. The calculator keeps waiting until you enter the radicand, then it calculates the root.
So before using the command you must know in what order to press the key sequence. If you get an error with a certain key order, do the opposite.

Now, why is the calculator giving you a syntax error always?. There could be may reasons.Try a simple addition or a multiplication. If you get a syntax error, it may be due the computational mode. You may be in statistics mode , or some other modes, I cannot begin to guess, because you say nothing about what you were doing when you get the errors.
Try to reset the calculator to get to default computational mode.

How do i type in the square root of negative 3 and get the answer. It keeps giving me ERR: SYNTAX


Use the (-) key next to the decimal point key to enter the negative sign, not the - key. The (-) key is for negative values, the - key is for subtracting one value from another.

Every time I try to graph on TI 84 it says ERR: INVALID DIM 1:QUIT I have enterered something simple y= x+2 and window is set for -10<x<10 and -10<y<10 the curser in y=...


Go to http://education.ti.com/downloads/guidebooks/graphing/84p/TI84Plus_guidebook_EN.pdf to download the manual. On page 401, you will find the following:
INVALID DIM • The ERR: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 y , and then select 4:PlotsOff. • You specified a list dimension as something other than an integer between 1 and 999. • You specified a matrix dimension as something other than an integer between 1 and 99. • You attempted to invert a matrix that is not square.

I also have Err: Syntax when i try to graph and i think thats because i use the regular MINUS but how do i use this '(-)' minus??


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

When i did y= and put in -x+3 for Y1 and (x-1) divided by -3 and hit graph, it says ERR:SYNTAX please help. im trying to solve linear systems by graphing.


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 (-)

My Graphing calculator has no x or y axis. Its all Blank.


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.
