Check your window settings (ZOOM, ZStandard gives the normal -10 to 10 for x and y). The Line(a,b,c,d) function draws a line from (a,b) to (c,d)

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.

When graphing the function (x+6)/(x-7) I'm getting a vertical line showing up on the graph connecting the two curves that shouldn't be there. do I have something turned on that shouldn't be?


The vertical line is called an asymptote, it is not connecting the graph, it means that the function goes to infinity as the function nears the line. In this case the graph goes to infinity and negative infinity as the x nears 7. This is because the function becomes undefined at x = 7 , plug 7 into x and we get 1/0, dividing by zero is undefined. Thus, the calculator puts the vertical asymptote in the graph to symbolize the action of the function nearing infinity.

How can i draw graph.


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.

Well when i put in the number for Y= then go into the graph it wont show me anything then after half a second it says error and undefined.


Reset the calculator RAM then draw a simple function such as Y1=X.
To reset the RAM:
  1. Press [2nd][+] to access the (MEM)ory management
  2. Press [7:Reset]
  3. [1:All RAM]
  4. [2:Reset]

Press [CLEAR] to erase the "RAM Cleared" Message.

  • Press [Y=]
  • On line Y1=, press the [X,T,theta,n] to type X or press [ALPHA] then the letter that has an X next to it.
  • Press [ENTER]
  • Presss the [GRAPH] key
You should see a line going through the origin (0,0)

My TI--84 plus calculator won't display the 7 graph modes, and it won't graph equations simultaneously. What is wrong? I can only get an arrow icon and an arrow-bar icon.


Hello,
Use the [Y=] entry screen to enter the functions you want to graph. Make sure that the = sign after Y1, Y2 etc. is highlighted (black). If the = sign is not highlighted the corresponding function will not be drawn. You can can up to 10 functions, but what is the point of drawing so many if they overlap?
Anyway, to change the graph style of the curve for a particular function, use arrows to move to the line, then use left arrow to the bit of line that appears to the left of the Y. Highlight the segment an press ENTER. Each time you press ENTER the style changes to another one. Beware of the unconnected bubble style. During the drawing it will show the position of the point being drawn, but at the end, the whole curve, so to speak, evaporates.
As to simultaneous graphs, if it is important to you to have the graphs drawn for all the curves at the same time, you can enforce that by pressing [MODE], and using down arrow to reach the 6th line Sequential Simul. Use the right arrow to highlight Simul and press ENTER.
Whether drawn sequentially or simultaneously, all graphs will be displayed, except for the ones with the unconnected bubble as style.

Hope it helps.

When i try to graph it says error and wont let me graph


Hello,
Reset calculator to defaults
[2nd][MEM][7][2][2] Defaults set.

[Y=] on line Y1= enter your function then press [GRAPH]
You can draw several graphs on the same screen.
If nothing shows (except the axes) use [ZOOM] to Zoom in or zoom out or use [WINDOW] to change the values of Xmin, Xmax, Ymin, Ymax.

Hope it helps.



Hope it helps
