After typing Mode+ and Graph, what do I have to type to display the graph of y=sin(2x)

Hi,
A 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
The service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
Good luck!

SOURCE: calculator won't graph right

try seeing if the mode is in radians or degrees, it must be in radians

Let me know if this works

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.

SOURCE: How do I type in

there should be an e to the x power button and to graph would be in y= button y=(e^-2x)+3x (^ stands for exponent spot) after putting this in to the y= hit graph

To enter powers of trigonometric functions you must enclose the functions in parentheses and then apply the exponent to the whole. For example X1t =(sin T)^3 , Y1t=(cos T)^3 will give you a shape similar to a rhombus with concave sides. The symbol ^syands for the operation of raising to a power. The key is the one with the caret symbol ^ , and it is wedged between the xsqure and EXIT keys (third row of keys).
As regards the cotangent, use the equivalent definition cot(X)=1/tan(X).

Testimonial: "thank you for your help sooo much u are a life saver and i was able to figure out how 2 graph the equations on my calculator"

SOURCE: When using my CASIO fx-CG10,

I may be imagining things, but I see curly brackets. That notation is reserverd for lists. Remove the brackets and you will see the graph.

Make sure you have the angular mode set to radians. In degree, the graph of sine(x) is nearly a straight line for small values of x.

### I think I pushed a button [2ND][+], and [ClrAllLIsts]. After that, I tried to draw graphs, but when I push the [GRAPH] button or [ZOOM][5]/[6], it doesn't make any graph! What should I do...??

You do not say that you opened the Y= editor and typed in at least one function and THEN pressed Graph. If you do not enter a function, all you will get are the axes (if the calculator is configured to display the axes.
1. Open the Y= editor.
2. Type in a function EXample y=2X+1 (To type X press the [X,T, Theta, n] key)
3. Press ENTER to validate the function.
4. Press the GRAPH button.
5. If you do not see a straigt line press the ZOOM button
6. Select ZoomSTD

### How do you do y equals 2x to the 4th?

Do you want to graph the function? y= (2X)^4 or y= 2*X^4.
If you want to graph it
1. Open the [Y=] equation editor.
2. On first line where it says Y1=, type the function using the [X,T,theta, n] key to enter the X symbol (the key is under the [MODE] key and above the [Apps] key.
3. Press the [GRAPH] key on the top right corner of the keypad.
If you want to do something else, you will have to be more specific, because DO is not precise enough.

### Graphing

Instruction book for this calculator is shocking for sure. It would take too long to explain fully, here is an example of plotting a simple Y= graph.

In main menu, when you first turn it on, press 1
This is normal calculator mode.
Press [shift] [menu] to get the set up parameters.
Scroll curser down one to Func Type, and select Y= if this is not already set, by pressing F1
Continue scrolling down to set Coord, Grid, Axes and Label functions. Turn these on or off as desired. Turn them all off for this example. F1 and F2 select On or Off here.
Press [exit]
Press [shift] F3 to access the V-window parameters. Here you set the size of the axis in the graph
Enter 0 for Xmin, 360 for Xmax, 0.1 for scale
Enter -1 for Ymin, 1 for Ymax, and 0.1 for scale
Press [exit]
Press [shift] F4 to enter graph plot mode (Sketch mode)
Press F1 then [EXE] to clear any previous graphs
Press F5 then F1 to select Y= type graph
Display should show Graph Y=
press [sin] [ X,0,T] (this key just under red alpha key) then [EXE]
Calculator should draw a sine wave, showing 1 complete wave
Try setting the parameters in Set up, Axes On, Label On etc to see the effect.
Hope this helps a little. Page 123 in book deals with graphing.

### I need to find out how to graph fuctions and the derivatives using a cfx 9850gc plus ASAP

Hello,
Let us start wih the derivatives. To obtain the values of derivatives at points on a graph, you must set Derivative to ON
Press [AC/On] to trun calculator on. If you do not see the icons press [MENU], with arrows select [RUN] and press[EXE] . The screen clears.
Press [SHIFT][SETUP ] . The first few options must be set as follows
Mode : : Comp
Function Type : Y=
Draw Type : PLot
Derivative : ON This is the one to make derivatives visible
Angle : Rad unles you have to use degrees.
Coord : on if you want the x,y coordinates to be displayed
Grid : Off
Axes : ON to display x and y axes
Press [EXE] to save options. You are taken to [Run] screen.
Press [Menu] Play with arrows to select [GRAPH] and press [EXE]

You see a list Y1=, Y2= and so on
On the line Y1=, enter [SIN] [X,Theta, T] .
If function is complicated you may have to enter parentheses sin(X). When you finish to enter the functions you want to draw, hit [F6:Draw]
The graphs are displayed.
Press [F1:Trace] The trace function allows you to move cursor along the curve, while it displays the coordinates of the cursor. And since you set Derivative to ON, the trace displays also the value of the derivative of the curve at the position of the cursor.

There are other intersting tools, under [Sketch] and [G-solve ] such as minimum, maximum, tangente, inverse of the function drawn, integral under the curve, intercepts with the coordinates axes, etc. I will not spoil your fun by giving you the plot of the movie.

Hope it helps.
