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:

SOURCE: graphing multiply equations

When you go to Y=, you should get a list that says:

Y1=

Y2=

Y3=

etc. You just enter the first equation into the Y1= space then hit ENTER and it will go to Y2=. Enter the second equation there. After you have entered all of your equations, push GRAPH and they should come up in order but they will all appear.

Also, make sure your window is set appropriately so that you are able to see all of the graphs.

Lastly, when you look at your Y= screen, are there funny looking arrows before the Y=? If so, do this:

Hope one of these are helpful!!

If you still have problems, just **reset the RAM**:

Press [2nd][+] (MEM). Press 7 to select [Reset] then [1:All Ram][2:Reset]. Press [Clear] to erase the Ram Cleard message.

Now you should be able to draw the graphs.

Hope it helps.

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.

You don't need "equal" to finish a operation, just hit ENTER.

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.

Hello,

To enter the inequation you split it into two inequalities

Graph is as follows

Use [2nd][CATALOG] to access the relaional operators less than or equal, greater than or equal, and the operator AND.

To access the inequality signs scroll upwards from abs( to reach the bottom of the catalog.

Note: You can use t as variable only in parametric graphs. Use x.

Hope it helps.
