Question about Casio CFX 9850GA Plus Calculator

Need to know graphing answers thanks

Hello,

Turn calculator [ON]. If you do not see the menu icons, press [MENU]. Use the arrow keys to highlight the [GRAPH] icon.

An entry screen appears where you enter the functions you want to graph.

On
the first line you have Y1= . After the equal sign enter 2[x] [X,
theta,T] + 1. When finished press [F6: Draw] Your graph appears on the
screen. If you see the axes, but no graph, press [Shift][V-Window] and
press [F3:Std] then [SHIFT][QUIT] will take you back to the screen
where you enter the functions to draw. There press [F6:Draw].

Hope it helps.

What does your graph look like? Do you have the proper angular mode set?

You can do it two ways.

**Graphically:**

Open the graph utility, enter a function y1= expression(x) where expression(x) is the polynomial. Graph the function y1(x). Play with the window dimensions to display the interesting part of the graph. You can then see if there are any zeros (roots).

While the graph is displayed, press SHIFT F5 (G-Solv). Press F1:Root to look for a root. Read the value of the root at the bottom of the screen (to the left).

**Solve utility**

Open the QEquation solver, select F2:polynomial, or F3: solver.

The polynomial solve can solve polynomial equations up to degree 6.

The solve solve polynomial and any other type of non algebraic equations

One simple way to define the domain to be graphed is to set the limits of the domain as the Xmin and Xmax dimensions of the window.

Although the coefficient of correlation is well defined for a few regression models, you do not calculate it directly because your calculator does that for you.

I could just tell you that it is displayed along with the statistical results (equation of best fitting curve, ) but if you do not know how to do that you will just shoot my post. If you know how to do a linear regression, stop right here and ignore what follows.

I am sorry but I will have to assume that you know how to enter the data through the [MENU][STAT].

On that same screen, you have a menu option [F6:Draw]. If you select it, the regression curve will be drawn on the same screen as your statistical graph. This allows you to judge if the fit is good. If it is not, you have the option to choose another model.

The other option [F5:Copy] allows you to save the regression equation in the Y1, Y2, etc. variables.

I am sorry but I will have to assume that you know how to enter the data through the [MENU][STAT].

- After you finish entering all the data
- Press [F1:Graph], select Gph1,
Gph2, or Gph3.
- Once the graph of the experimental data is drawn, you
will have access to the diverse regression models.
- Your choices are
- [X:Linear]
- [Med-Med],
- [Quadratic :X^2]
- [Cubic;X^3]
- [Quartic: X^4].
- Press [F6] to scroll right to access the others
- [Logarithmic:LOG],
- [Exponential :EXP],
- [Power :Pwr] and
- [Sinusoidal: Sin]

On that same screen, you have a menu option [F6:Draw]. If you select it, the regression curve will be drawn on the same screen as your statistical graph. This allows you to judge if the fit is good. If it is not, you have the option to choose another model.

Hello,

Use the key [x, theta, T] below the [Alpha] key, or use [ALPHA] [+] (x)

Hope it helps.
