How do I graph sinx on my Casio fx-9750GII calculator?


Turn calculator ON
If you see no icons, press Menu
Press 3 (Graph) draw your function. (more on that later).
If the first line of the display show Graph Func : Y= you should be able to draw your function.
If it says anything else, press F3 TYPE to select the graph type and select functional by pressing F1 key Y=.
After the graph type is set to Y=, type the second member of your function y= f(x) on the first line. Make sure the = sign after Y1= remains highlighted after you move cursor. Otherwise select the function by pressing F1:SEL. Press F6 Draw.
Be careful with trigonometric functions. If angle unit is radian, set window Zoom to standard. If angle unit is degree, you must open the Window utility and set Xmin=-190, Xmax = 190 to see at least a period.

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.

You do not say if you get any error message.
Try to reset the calculator Press [2nd][+] to open memory management.

Then open the Y= editor and to the right of Y1= type in [X,T,theta,n] and press [ENTER]. You will see the straight line y=x.
Please report back what you get.

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.

Graphing problems


Hi,
From what I understand you want to draw statistical graphs (scatter plot, box plot, etc.) and you window is set up correctly. Usually, one must first see agraph and adjust the window, but no matter.
If you do not see anything it may be due to the fact thea the statistical plots are turned off.

Type in the data in lists L1 and L2, etc. Press [2nd][QUIT]

Press [2nd][Y=] (STAT PLOT] . Select [4:PlotsOff] [ENTER] .
Screen displays Done

Press [2nd][Y=] (STAT PLOT] . Select [1:Plot1 Off].
  1. The configuration screen for Plot1 opens with the cursor blinking ON.
  2. Press [ENTER] to turn Plot1 ON.
  3. Use Down Arrow to move cursor to second line Type:
  4. Select the type of statistical plot. Use the right arrow to move highlight on one of the 6 types.
  5. Select the type:scatter, Xline, histogram, box plot, and press [ENTER] to validate the choisce.
  6. Use down arrow to select the Xlist: use [2nd][1] to choose L1, etc. and press [ENTER]
  7. Select the Y-List (L2) and validate by pressing [ENTER]
  8. Select the data-point mark.
  9. Press [GRAPH].

Problem using graphing on my casio


This calculator has so many options you can change, that it is possible one of them has been altered. Try pressing the master reset button at the back to re-set the calculator. Note that you will lose all your programs and data, so first copy out anything important. Also, set the xmin and xmax parameters to a higher value. To plot a sign wave, try xmin=-720, xmax=720, step=1, ymin=-1, ymax=1, step=.1 The step value won't change the appearance of the graph, just make it more chunky or fine. Use the equation y=sin x. This should draw a sign wave showing 4 complete waves. PS when you enter the X in the equations, you are pressing the X,0,T button, the one under the alpha key, aren't you? If you enter X using the x alpha key, it won't work. Also, to plot y=, make sure you change the func type parameter in the Set Up menu to y=. Hope this helps.
