Question about Casio fx-300ES Calculator

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.

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

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.

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=

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.

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.

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.

Your assumption

--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.

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

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.

- Press the [APPS] button, find Inequalz or Transform, point to it and click [ENTER].
- You will be asked to Continue or Quit the application.
- Press the number corresponding to Quit (usually 2).

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.

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!
