How do you use the equal sign on the ti-84


The equal sign of the TI83/84/Plus is a relational operator like less than , greater than, less than or equal to) You use it when you are testing if two values (numbers, expressions, or matrices) are equal.
For example, if in one your programs what you do at a certain time depends on the equality of two expressions, you test the equality by a statement :
If A=B do this action.

How do you type an equal sign on the TI 84 calculator


On these units, the "equals" sign ([=]) is located in the [TEST] menu. This menu is a [2nd] function of the [MATH] key.

This function is used to test if two expressions are equals. To evaluate an expression, simply hit [ENTER].

Good luck.

5/4x-18=-3 Ti 84 plus One: just press enter/solve Two: press 2nd Test (Math) then press enter Every time I put in and equation using the above method for the equal sign. it either takes me back to...


If you wan to solve an equation using the SOLVE feature you enter it as follows (your example)
You should rewrite it as 5/4*X-18+3 (= 0). Implicitly, the calculator assumes that the right side is ZERO and you do not enter any right side nor an equal sign.
Type in
5/4 [*] [X,T,theta, n] -18 +3 [ALPHA] [ENTER] (SOLVE)
You should get an answer -780/47 or the decimal equivalent (depending on display mode.)

Where is the equal sign on the ti 84 plus


hello sir, Press "second" "math", and it should be the first thing listed. If you need other commands hit "second" "0" that will enter the catalog and you can press any letter (without hitting alpha) to jump to that letter in the list. Please click on the following link to see the manual of the TI-84 Plus Calculator: http://education.ti.com/guidebooks/graphing/84p/TI84PlusGuidebook_Part2_EN.pdf

How do you use a plus or minus sign on a TI-84


Hi,
You cannot use the ± in the definition of a function. If you need to consider two alternatives, you have draw each function separately, one function as Y1 and the other as Y2. I just checked the catalog of commands, and there is no ±.

Hope it helps.

TI 84 plus calculator refuses to graph more than one function


Hello,
Please, read the following, even if you already know some of its contents.
  1. Once you enter an equation, the corresponding equal sign is highlighted by default.
  2. Before you draw the 2 graphs, move the cursor to Y3 or Y4 and verify that the = signs for Y1 and Y2 remain highlighted.
  3. If one is not highlighted, move the cursor on it and press ENTER.
  4. If you still have problem, press [2nd][STATPLOTS][4: PlotsOff] [ENTER].
  5. Command PlotsOff echoes on main screen.
  6. Press [ENTER], screen displays Done.
  7. Restart the graphing procedure.
  8. If all else fails, just reset the RAM by pressing [2nd][MEM][7:Reset][1:All RAM][2:Reset], press [CLEAR] to clear the message.
You should make it a habit to clear the RAM every time you start a new type of problem.

Hope it helps.
