Graphing doesnt show


Depending on the function you are drawing, it is possible that the graph is out of range of the windows dimensions. Try Zooming out to see a bigger portion of the plane. If you know where the function intercepts one of the axes, you might want to center the graph around that point.

How do I get more than one graph to graph? The calculator is stopping me from turning more than one graph on.


After entering the first function to graph press the down arrow and when the cursor blinks after Y2 type in the second function you wish to graph. After you finished entering multiple functions make sure the graph setting under the window button are set correctly so every function will be visible at the interval you set. After that you hit Graph and you should see your graphs being plotted.


I hope it helps.

How do i graph?


The fact that you are asking how to graph makes believe that you solved the problem about 'invalid dimension' . I am glad that worked for you.

This
should help you setup your calculator to do graphing.

1. Prepare calculator for graphing
Turn StatPlotsOff to avoid errors:

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

2. Setup Graph type
  • Press [MODE] key.
  • In Mode set up screen, make set the angle unit (if you are drawing trigonometric functions)..
  • Use the arrows to move cursor to 3rd line to highlight degree or radian and press [ENTER]. The important thing is that you be aware of the unit so that you do not get unexpected results.
  • On same screen, verify that Func is highlighted. If you are drawing PARametric plots, POLar plots or SEQuence plots, you highlight the relevant item in the list
  • If it is not, use arrow to highlight Func and press [ENTER] to validate.
  • Do not worry if you do not have exactly the same screen as in the screen picture (We may have different OS Versions)

3. Entering the functions to draw (assuming you want to draw y= functions)
  • Press [Y=] to enter function editor.
  • Type in a function
  • Press [ENTER] at the end of each function.
  • Before pressing [GRAPH], make sure that all the = signs that define the functions to be graphed are highlighted white on black. If one is not highlighted, use arrow to move cursor on the sign and press [ENTER].
  • In the screen capture 4 functions are slated to be drawn.

4. Selecting the Graph Style (You may ignore this now, because it is unimportant for just one graph)
  • Select the graph style: The small piece of line to the left of a Y that defines a function is the style.
  • Move cursor on it and press [ENTER] .
  • Each [ENTER] (on same line) selects another style.
  • On the next screen you have all the styles available on the calculator.
  • Do not select the bubble on line 6: It is for animations. It will not leave a trace at the end of the plot.

5. Drawing the Graphs
  • Press [GRAPH] to see the graphs.
  • If one of them is missing, verify that its = is still highlighted, then use the [WINDOW] to set the Window dimensions,
  • Here are the dimensions of the standard window

6. ZOOMING
You can also press [ZOOM] to adjust.

The selection 6:ZStandard sets the dimensions as on the screen Titled Window (above).

How to use graphing calculator?


The casio FX-300Ms calculator cannot do graphs. To tell you how to use a graphing calculator TO DRAW GRAPHS we need to know the exact brand and model number of the calculator.

  1. Most graphing calculators basically function the same way.
  2. You select the graph type (function, polar,parametric, sequence, 3D, wire mesh, slope field, etc.)
  3. You enter the algebraic form of the function you want to draw.
  4. You press a button or menu to GRAPH
  5. The graph is drawn.
  6. If you want to see a particular part of the graph, you use a ZOOM function, or you enter values for the WINDOW dimensions.
  7. Most graphing calculators have a TRACE function that allow you to follow the curve you have drawn to read off values of coordinate points.
  8. You can also use the calculator to find zeros roots) of functions, calculate derivatives at some chosen points or calculate the area "under the curve", find the minimum and maximum of a function.
In addition to its graphing capabilities, a graphing calculator can be used as a scientific calculator. Sometimes it can also do statistical and financial calculations, matrices, list manipulations, operations on complex numbers, text editing,, creating programs etc.

Solve for x-intercept and graph:f(x)= -x^2 + 2x - 1


Graph the function then use the trace function to locate the point(s) where two curves intersect. In your case one of the curves is the X-AXIS.

See the screen capture to learn how to use the trace functionality.

Hello,

Turn calculator. Use arrow to highlight the 2:Graph and Geometry application. Enter your function at the bottom of the screen. Use TAB to move focus on command line.
Press [ENTER] to graph.
While graph is drawn, press [menu] key. Select [5:Trace][1:Graph Trace] . An X appears on the graph screen. Use arrow to move cursor towards one of the zeros you see. At some point the calculator will pop up the label [zero]

The value of the secon zero is also displayed.

You can also the nSolve command

Use the nSolve( function available in main calculator application. Here some exemples of syntax

On the second command line, the small vertical segment after the right parenthesis is accessed by the key sequence [CTRL] [infinity, beta, degree] key, the one under [left arrow/clear].

No graph appears?


did you make sure the domain, range, and scale settings are correct?

Graph and trace buttons don't work


This is probably because you have the stat plot on. You would need to go to y= and then go to the top where it says stat plot 1 and un highlight it if it is highligted. That should fix your problem.
