The Y-values listing is missing under the [2nd] graph button. Only the

ok,
I assume that you are attempting to make a scatter plot of some sort. Here's how:

Instead of hitting the [table] button. You should hit the [stat] or [stats] button as I forget which it is. Then hit [enter] which will bring you to a stats list editor of some kind. You will want to enter the data for your x-axis in L1 and the data for your y-axis in L2. Once you have completed your lists, hit the [stat] button again and then click [right] or the right arrow in order to move to the section of calc. from number 4 down it will help create a graph of that type of function. lets say you think it is linear, so you hit [enter] on number 4 and then you will be at the home screen with LinReg already written. You just have to complete the statement and it will do it for you. hit the [2nd] [1] and then the comma button, then [2nd] [2] and [enter]. that will do it for you.

If I am mistaken in my thoughts and you have a graph that you need the points of, type the function into the y= menu or solve a few points and do the above suggestion.

The calculator will not allow you to plug-in values for the y within the table menu.

I hope this helps.

Turn StatPlotsOff
Press [2nd][STATPLOT][4:PlotsOff][ENTER].


Calculator answers DONE.
You can Clear All Lists:
Press [2nd][0] to access the (CATALOG) of commands.
Scroll till you reach ClrAllLists

OR
press [PGRM] to jump to the first command in CATALOG that starts with C an then scroll to ClrAllLists

OR
Press [2nd][+] to open mempry Management and select [4:ClrAllLists]

Command echoes on main screen.
Press [ENTER]
Calculator answers DONE.

Draw your graphs now.

This usually happens after the statistical graphs have been used. You should deactivate them. Press [2nd][Y=] (STAT PLOT). Select [4:PlotsOff] [ENTER]. Calculator echoes Done on main screen.
Restart your graphs.

Your poor calculator just can't seem to fit the values you want onto your graph without risking unsightly stretch marks. To fix this, either press the "ZOOM" key and return to "ZStandard", or press "WINDOW" and define more acceptable (or possible) dimentions.

Hello,
Sorry if you already know that, but I want to make sure we understand one another.

Say you want to graph the function Y1=2X+3.
You press [MODE] to make sure that the FUNC on 4th line is highlighted permanently. If it is you press [Y=]

On the first line where it says Y1= you enter 2*[X,T,Theta,n] +3.
The X is accessed with the key to the right of the [ALPHA] key.
As you key in your function, notice that the equal sign after Y1 is highlighted and remains so. When you finish entering the function press [ENTER] so that the cursor moves to the line Y2=. Make sure that the = sign after the Y1 in previous equation remains highlighted.

You can now draw the graph by pressing [GRAPH] or generate the table Y1=f(X) by pressing [2nd][TABLE]. Under no conditions should you enter YOUR own values. If the table does not appear there may be a problem, and you will not solve it by entering values.

Now let us try to get you calculator to work as it should.

Press [2nd][STATPLOT][4:PlotsOff] , the command PlotsOff echoes on main screen. Press [ENTER] to turn statistical plots OFF. Screen displays Done.
Press [2nd][CATALOG] [ENTER]. The list of all avilable command appears. Scroll down till you reach ClrAllLists. Move arrow to the correspondig line and press [ENTER] , command echoes on main screen as ClrAllLists. Press [ENTER] to erase all old statistical lists that may be stored in the calculator memory.

Now you are ready to graph or create the table of values. Press [2nd][Table] and the table should be displayed. All you can do with the values in the table is to look at them, examine them. You cannot modifie nor erase them.

If, for reasons of your own, you think you ought to be allowed to enter YOUR values, in the table, then this is not graphing functions. The name for that is DOING STATISTICS. And the procedure is tottaly different: You enter YOUR values in lists and use the calculator to draw the data points, and to find the best fit (the curve that models the pattern of data distribution best). When you decide which fit is the best, you can use the calculator to extract the equation for the curve and, if you want it, to draw the curve on the same graph where you raw data is represented.
Hope these clarifications helps.





Before jumpin

Hello,
It is noranl that you cannot enter data in the table becuase it was generated from the function you entered. If you specify the function you cannot specify the data in the table. But if you want to enter you own values, that is doing statistics, not graphing functions.
To do stats
Press STAT button, then select 5: SetUPEditor ENTER ENTER. You do that to reset calculator to do stats.
After that press STAT again, and select 1:Edit. The lists open to you and you can enter your data in the lists

But not knowing what you really want to do, I cannot advise you better.
Hope it helps.

Hello,
1.Press [MODE], scroll to set Function graphing mode.
2.Press [STAT] [5:SetUpEditor], command is pasted in home screen. Press [ENTER]. Screen displays Done. This clears old values in lists

3. Press [STAT][1:Edit] to enter data.
Press [ENTER] after each number. Cursor moves to next row. After finishing the data of Listt L1, use arrow right and UP to the head of list L2. Enter the values in list L2. Press Enter after last element.

4. Press [Y=] to display Y= editor. Clear function Y1 and all functions or remove highlight from the = in Y2, Y3, etc.
5.Press [2nd][STATPLOT]1 to select 1:Plot1


The blinking cursor on ON means graph will be drawn. Type chosen is Scatter plot. Mark chosen is a dot.

Press [ZOOM][9:ZoomStat]

If you think that the curve look like a straight line you can try to do a linear regression.
Press [STAT] Arrow right to highlight [CALC]
Select [4: LinReg(ax+b)]



LinReg(ax+b) echoes on run screen. Press [2nd] L1 Press comma, Press [2nd] L2 press comma Press [VARS] Arrow right to select [Y:VARs][1:Function] [ENTER][1:Y1]

ENTER

That is the equation for the linear regression. As you see eqaution has been saved in Y1. Press [GRAPH] to get the data and the regression curve drawn on same graph.


Hope it helps.

hit 2nd y= and edit your stat plot to make sure you have the right stat plots turned on or just make sure that there is an x and y for EVERY value of your stat plots

If you have more than one function graphed, use Up/Down to select the one you want. Press Left/Right to select the point at which you want the derivative, then press ENTER to see the value of dy/dx.

you should first put it in the form y=mx+b
m-slope
b-y-intercept
x + 2y=4
-x -x 1subtract x from both sides

2y=4-x
/2 /2 2 divide both sides by 2 (to get y alone)

y=2- x/2 now you can put that into your calc. (Y= button)it would like like this on your screen Y1=2-X/2 (X is found under mode)
next hit graph

2nd, TABLE will give you a list of x-values and y-values
hoped i didn't leave anything out and i hope this helped
