Question about Texas Instruments TI-89 Calculator

Hi. I'm not sure if you are using the correct button for a negative integer. I do this all the time, but the first thing to check is that you use the button that is located next to the decimal point (very bottom row, second button from the right) it looks like (-). If you are using the actual "minus" button thats in the same columns as + and x, etc then you will receive a syntax error.

so try 5*(button next to decimal (-)1) and you should hopefully get the right answer and error free :)

If that is not the case then I'm not quite sure how to help you

Please give the exact examples you were trying to graph. The syntax error points to an error in the input line, such as using the minus sign instead of the change sign (-).

Error 07 Syntax

Means you made a typing error while entering the equation. Using the minus sign instead of the negation sign (change sign) (-), can produce a syntax error. Maybe you need to explicitly type the multiplication sign

y= (-) 1.5*x +3

Try entering it as 3 - 1.5*x

You enter a command. It is like an English sentence with a syntax (correct structure). If the structure of the command is wrong, you have a syntax error. You could use a minus - sign, instead of a change sign (-) that constitutes a syntax error.

Hello,

The calculator has two minus signs

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

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.

Do not forget to rate the solution

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 --

Hello,

Calculators usually have two minuses, the regular minus sign and the change sign sometimes labeled (-) or (+/-). The latter is not meant to effect a subtraction, but to take the negative of the number you just entered. Big difference, would you say, but the syntax is different.

Ex: 15 - 7 is a subtraction with result 8

10 (-) displays -10 on the screen.

In some calculators the change sign is smaller than the regular minus, and is raised above the main line.

Hope it helps.

Hello,

The calculator will stop screaming out SYNTAX ERROR, when you stop ordering it to do things the wrong way.

Take a look at the manual.

For certain calculations you enter the number first and then press the function key.

For others, you press the function key then the number.

If an expression contains a left parenthesis, it must also have a closing right parenthesis.

It you want to enter negative 5, you use the change sign (-) not the regular MINUS sign.

These are exemples of instances where you get a syntax error. For every new type of calculation you have to perform, read the exemple in the manual to find out which must be entered first: the number or the function.

Hope it helps.

Hello,

I am no seer, nor will I try to guess what may have happened. This error may come from various conditions

1. The most common reason is an omitted right parenthesis. For instance you press the [sin] function key. It shows as sin( , notice the right parenthesis. You enter the variable, say X, and you press [ENTER]. The calculator gives you a syntax error: It does not know what to do as long as you do not insert the closing parenthesis.

2. Another common source of this error message is the use of the regular MINUS sign instead of the (-). The latter appears on the scren as a smaller, raised minus sign. This is especially true when you want to raise a number or a variable to a negative exponent.

Every function has one way it takes in its food (argument). If you don't do it the right way, it gives you an error. The nice thing is that the calculator gives you the opportunity to correct the error. Whenever you see Error 1:quit 2: Go to, choose GO TO because the calculator shows you exactly the symbol that is creating havoc: It will be highlighted.

Hope it helps.

Hello

To calculate a number to an arbitrary power you use the button labeled ^ .

If you want the cube of 2 your enter

[2][^][3] will give you 8. If your exponent is negative use the sign change key (-) and close the negative exponent between parentheses : for exemple the sequence to compute 2 to power of negative 5 is as follows

2[^] [(] 5 [(-)] [)] which means you enter the value of the exponent before the change sign (-). If you use the big MINUS sign you will get a syntax error.
