# I have a lot of numbers on the starting and ending points

When i go to the table and type in an equation for my table the starting and ending numbers come up as something like 1.000000000x10 to the power of 0, why?

Hello,
Regardless of the way it looks, this huge number is just 1, written in scientific notation, with 9 decimal digits. This is due to the configuration of your calculator.
To revert to the default display mode, press [SHIFT][MODE][6:Fix] and select a number of decimal digits between 0 and 9.
If you do not like the [MathIO] (fractions, radicals) you can use the [SHIFT][MODE][2:LineIO]
Hope it helps.

Hi,
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
goodluck!

### How to solve and graph the equation 4x+y+0

The easiest way to solve and graph and equation is to put the equation into the slope intercept form y = mx + b, where m is the slope and b in the y-intercept.

To do this, we subtract 4x from both sides and get y = -4x + 0.

From this we know m = -4 (slope) and the y-intercept is 0.

I always start with the y-intercept and put a point there. Thus, we have a point at (0,0). Using this as a starting point, we now use the slope of -4 to get future points. Since it is negative, we go one unit to the left and up four units. So we have the point (-1,4). Using a ruler, we connect these points and continue on both sides to produce the line.

There is also a great free online program/app called Desmos that you can use to check your work. Type in the equation of the line and it will graph it for you.

Good luck,

Paul

### Save equation fx 991es

In table Mode you can enter the formula for a function and generate a table of values. For a 991ES Plus you can enter two functions. However if you change MODE everything will be erased.
In EQN (equation) there is a certain number of built in formula types you can choose. You will be asked for the coefficients which will be used to solve the equation selected. However if you change MODE your lose what you entered. So basically you cannot save formulas to use as a memory aid (if that is what your intention is.) Sorry.

### My Casio fx-9750GII wont dispay a table

The message dimension error usually refers to instances where two lists do not have the same dimensions (number of elements)
I checked and the calculator gives condition error. Check the type of function you are creating a table for. Choose the type y=

### Solving linear equations in 3 variables by matrix method in casio fx-115ES

Press key Mode, first select option 5:EQN (by pressing key 5), then option 2: a_nX+b_nY+c_nZ=d_n (by pressin 2).
Now input coefficients from equations in table (each column is for one variable), just type in number and press =, then use arrows to move to another cell.

### How can I compute quadratic equations using fx-300ES?

You cannot solve the quadratic equation with this calculator. It does not have a solve program.

However if you wnat to create a table of values for a function (any type of function that uses the basic scientific function keys ) you use the TABLE Computational Mode.

You press MODE
You select TABLE
You enter a mathematical expression 3X^2-.33X+ 15
You generate the table of values.

### My calculator casio fx-350ES doesn't have equation.why? or this calculator doesn't have software equation.why?

Not all calculators have that. The Fx115ES and the FX991 ES have a lot more options thatn the FX300Es and FX350ES. I believe you only have COMP (general computational mode), Table and STAT.
Why? It was not designed that way.

### I have a TI-84 plus calculator. I enter data into a table (L1 & L2) and go through the steps to get an equation for the data. Next, I should be able to press VARS, move to Y-VARS, select FUNCTION,...

--Next, I should be able to press VARS, move to Y-VARS, select FUNCTION, then select Y-1 and automatically enter the equation into Y-1.-
is not correct.

When you press [STAT[>][CALC][4:LinReg(ax+b)] or any other regression model,the command echoes on the main screen. If you press [ENTER] at this point, the calculator uses by default lists L1 and L2 and displays the resulting equation without copying it in a Y-variable.

If you want to have the equation copied on a Y-function, you should modify the command as follows
LineReg(ax+b) [SHIFT][1: L1] [,] SHIFT[2:L2] [,] [VARS][>:Y-Vars] [1:Function][1:Y-1][ENTER].

Here, [>] stands for RightArrow. For any other regression model, use the appropriate command.
At this point, the command line should look like the following:

LinReg(ax+b) L1, L2, Y1

Press [ENTER] to calculate you get the same screen as when you do not save the equation in Y1, but if you go to the Y= editor or press GRAPH, you will see the regression line superposed on the scatter plot.

### I am trying to see 2 different tables on my table screen from 2 different equations, but it when i go to the screen, instead of showing 2 different tables, it only shows one of them. I also noticed that...

Hi,
In the Y= equation editor you can enter two functions, and graph them both or calculate a table for both. However, the two functions will be evaluated at the same values of X.

Rather than trying to guess what is happening, I will show you how to get your two tables.

If you have used one the applications Inequalz or Transform it si probably still stuck in memory, and you must unload it from the RAM before recovering the usual calculator behavio(u)r
1. Press the [APPS] button, find Inequalz or Transform, point to it and click [ENTER].
2. You will be asked to Continue or Quit the application.
3. Press the number corresponding to Quit (usually 2).
4. Press [2nd][Y=] (STAT PLOT). Press [4:PlotsOff][ENTER]
5. Calculator replies Done.
Open the [Y=] equation editor. Type in your equations. Press [ENTER] at the end of each equation. Verify that the [=] signs after Y1, and Y2 remain highlighted when cursor is moved away from them.
Press [2nd][GRAPH] (Table) to see your 2 tables y1 and y2 calculated at the same X.

Hope it helps.
Thank you for rating the solution.

### No Y's in Table

The tables will not say Y specifically, they only say L1, L2, L3, etc. UNLESS you type in an equation in the "Y=" button menu. When you type an equation in on that page, and then hit "2nd" "GRAPH", you will get X and Y values for that equation.

### Singular matrix error

I had this problem as well...Were you working on a SinReg equation by any chance? I was able to do every other type of regression (Linear, quadratic, cubic, ect..) In order to get Sinusoidal regression you need to make sure you arrow down to the Period box when entering the equation, and fill it in with the number of items in your table of values (a ten item list means a period of 10). That was the fix for me, so hopefully it works for you!
