My Casio FX-9860II calculator won't connect to the computer!

Change the graph type from parametric to function.
Press the Menu key then Graph. The type is displayed at the top Param.
Press the TAB Typ, then F1 to activate Y= type.
See the screen captures below.





When the default type is Y=, pressing the key X,Theta, T enters the varaible X.

Unfortunately, the Casio FX-9860 G does not have a Computer Algebra System or CAS. For this reason it can only calculate definte integral over a given interval. The lower and upper limits must be supplied. The result will be a number.
Casio calculators that have a CAS are the Casio ClassPad CP330/ 300Plus/ 330, or the Algebra FX 2.0.

You may be using the wrong cord, or you may lack the proper software to use it. If this is the case then you can get it from the link below.

Using the Windows calculator in scientific view, we get:
17^23 = 19,967,568,900,859,523,802,559,065,713
which is 29 digits long, ie much longer than the capacity of most calculators.

Because both 17 and 23 are prime numbers, it isn't possible to simplify this calculation, so you will need to use find a calculator that has sufficient capacity to be able to handle numbers of this length.

The xnumbers add-in for Microsoft Excel can also be useful for this sort of calculation (do an internet search for it).

Using the Windows calculator, MOD55 of the above number is 18.

I compared two cables and noticed that they are identical. One insulating part on the TI cable is longer than the corresponding part on the Casio cable. But no matter, let us assume that the calculators share the same 2.5 mm connection.
You can verify the hardware compatibility as follows

1. Use the Casio I/O cable to connect two TI calculators. The Casio cable wakes up the TI84PLus
   
2. Use the TI I/O cable to connect to Casio calculators. The TI cable wakes up the Casio FX9550GII but not the CFX-9750GPlus nor the Graph 35. But that may not mean too much.
3. Create a Matrix ( a 3X3 ) on one TI8xPLUS and transfer it to another TI8xPLUS using the Casio Cable.
4. Create a small (3x3) matrix on one Casio C/FX-9750G/PLUS and transfer it to another C/FX-9750G/Plus.
5. If you have been successful in any of the above you may try to transfer an object from a TI to a casio or from a Casio to a TI and the cable that worked above.

My feeling is that you cannot. I tried it
When I tried to transfer from a TI to a Casio, the Casio kept displaying RECEIVING , AC to cancel. The TI returned an Xmit ERROR
When I tried to transfer from a Casio to TI, the Casio quickly returned a Transmit Error, while the TI kept waiting for a transmission.

There may be other issues of memory organization, naming conventions, systems commands and program commands so on.

For each problem you want to have your students solve try to supply the procedures for both types of calculators. This, in my opinion, is the reasonable way to go. A benefit to you is that you learn the expert use of both types of calculators.
If you care to specify what kind of programs you intend to transfer from one to the other, one may be able to point you to some resources available on the web.

here you are Melanie. There a few!

2 causes for this kind of problem:

1. lose battery contacts
2. poor connection on its components on the motherboard. (needs to resoldered)

I just bought mine and ran into the same problem. The fix is easy. First you need to make sure that the software is correctly installed. I installed mine and when trying to connect, couldn't. I had the unit turned on.

a. Because of reading the manual, I turned off my calculator - reconnected it to the computer via the cable. Had the CD (Casio CD) in the drive. The computer reinstalled the software after it auto-turned on the calculator and it worked.
-------
b. Next time I ran into the problem. I had just had it connected to the computer and was editing a program. I exited the calculator and later tried to re-connect and couldn't.

I found that I had to make sure that the calculator is off. Also, you have to make sure that on the software (if it is open all the while) you hit the button at the left side window for the calculator that tells it to disconnect. If it is shown to be disconnected, the connect the calculator while off. It will auto-connect. The rest is easy.
