SOURCE: How do I graph an equation such as y= 5x + 2?

Hello,

Turn calculator ON. If you do not see several icons press [MENu].

Use arrow to select the [GRAPH] application and press [EXE].

In the entry screen, the line with Y1= is highlighted. If it is not, use arrow to highlight it.

Press the right arrow, the highlighting disappears leaving you with Y1= and the blinking cursor.

At the position of the cursor enter 5 [X, theta,T] key under the [ALPHA]. On the screen appears 5X, complete you equation +2.

Press [EXE] to store function.

If you want to draw other functions, it is time to do so on that screen.

When done press [F6:Draw}.

If the screen does not show a lot of the function, you can use the arrow keys to pan the graph.

You can also press [SHIFT][V-Window] to set the window limits.

Hope it helps.

To draw graphs.

- Turn calculator ON (isn't that obvious?)
- If you see no icons, press [MENU]
- Use arrow to move focus on GRAPH and press [EXE]
- By default, the graph type is Y=
- Enter your equation on line Y1=, use the [X,theta,T] key to enter the X-variable
- Press [EXE] when finished entering a function.
- Enter other functions if you want.
- When done, press [F6:Draw].
- If you do not see a big portion of the curve you can press [SHIFT] [F2:Zoom] and select [F5:Auto]

This last one is obtained with the Zoom: Auto

SOURCE: i do not know how

Hey it is. Okay, so start with a equation: say, y = -(1 |x|). Now type y = -(1 , then press the [OPTN] button, next to the shift. Next press the [NUM] button or F5. The first menu button should be Abs or absolute value. When your done it should look like this. y = -(1 Abs (x)) then graph it.

You'll find the absolute value function in the MATH menu.

Press Menu.

Use arrows to highlight STAT icon and press EXE.

Enter your data in two lists (x-values in L1, Y-values in L2)

Press F2 to activate the CALC Tab at the bottom of screen.

This is what you see.

Press F3 to activate the REGression tab.

This is what you will see: the TABs at the bottom of screen.

Each tab corresponds to a regression model: X-linear, X2 quadratic, etc.

If you press F3:X^2, you get the following

You see the parameters of the regression equation, the coefficient of determination r^2, and the Mean Square error. No correlation coefficient is defined for this regression model.

For other models like linear, logarithmic, power and exponential regressions, the correlation coefficient is defined and is thus displayed with the regression equation. It is the r-value.

When it is time for you to put an expression in absolute value, press the OPTN key, then F5/Num, then F1/Abs. Open parenthesis, input expression, then close parenthesis.

For fractions, use the key with the symbol a b/c.

A little friendly advice, please do invest some of your time reading the manual. Most Casio graphing calculators work the same way. What you learn on one, works on another.

In Casio Graphing calculators, MA error stands for Math Error. The calculation overflows the memory.

Check the calculator with a simple 2X2 matrix that you can invert by hand easily and see if it gives you the wrong inverse for it. It is also possible that YOU made the mistake.

Your function is not correctly defined. If graph is function y=f(x), variable must be x; if graph is polar, variable must be theta, and if graph is parametric, variable must be t. This does not cover all possible cases. **Check the graph type and the definition of the function.**

They're both giving you the same number.

1.953125E-03 means 1.953125 * 10^-3, which is 0.001953125 .

Please give the exact examples you were trying to graph. The syntax error points to an error in the input line, such as using the minus sign instead of the change sign (-).

Your calculator cannot, natively, perform 3D graphing.

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=

Sorry but you cannot do that. This is not a graphing calculator. However you can generate a table of values for your function (MODE TABLE) and use it to graph the curve by hand (pencil and paper).

If you need a Casio graphing calculator, one of the cheaper ones is the Casio FX-9750GII. Equivalent Texas Instruments calculators are the TI83PLUS/TI84PLUS.
