Casio(R) FX-9750GPlus Graphing Calculator

I purchased this Casio because it was a lot cheaper then a TI83/84. In it's advertising it says it does the same functions but I am finding that it does not. When it does do one of the functions it is off by it's rounding or it doesn't come up with the same type of answer (different form like decimal) which I have to then translate to the correct form. For me it was not worth the price break.

This Graphing calculator is the model that my son's school requested. I can see why. It has all of the functions needed to help him perform in Geometry as well as chemistry class. If you need a good graphing calculator this is a great buy.

I have used this calculator for 3 years, and it been of great service to me. The icon-based UI makes things much easier to find and use (there are also hotkeys you could push for faster access, they're on the lower right corner of the icons). I like the screen, it has blue on green text, and it's a higher resolution than the TI-83 (I haven't seen the screens on the newer TI models). Overall it is more user friendly, with some exceptions: instructions in math class, and programs and games. Most if not all math textbooks have instructions for TI calculators, which dominate the education market. There aren't games that are graphically based like the TI calcs (Then again, you shouldn't be playing games during class), also programming is somewhat annoying to do, because all the options are handled by the Function keys. I prefer the Casio over TI (based on the TI-83, I haven't tried any other models), because of its user friendliness, and its price.

I have used this caculator for about half a year now. it works wonderfully. it takes a while to learn all the functions and notations and stuff, but once you do, it is so cool. i use it for my math class now, and i am super pleased. i am also glad because it seems very durable. i dropped this thing so many times, but it hasn't broken yet. overall, i would reccommend this to anyone who is looking for a graphing calculator that doesn't mind taking time to learn the fuctions/doesn't care that the screen is black and white. my only problem is that it can't really do inequalities.

Very specific instrument. If you need a graphing Calc, in my opinion this is the best "cost efficient"

I would love to write a review but as of right now I have not yet received this product.

I am a math teacher at a new private Bronx high school, and compared the TI-83 with the Casio in numerous regards before deciding which one our school would use. Hands down, the Casio wins, and it is cheaper as well. Note - I do not work for Casio or TI.
A) The calculator is more user friendly. The options are menu driven in a more intuitive way. What took me a minute or two to locate and figure out out the TI, took less than half the time on the Casio. Don't trust me- see for yourself.
B) The Casio is slightly faster than the TI
C)Features: The casio adds a dynamic graphing system (lets you change a coefficient and watch the graph change), which is very useful when teaching. I also like the EQUA feature, which lets my students calculate 2/3 equations, 2/3 unknowns, and solve quadratic or polynomial equations. Maybe the TI does this too, but I couln't figure it out.
D) The color thing I suppose is nice, but I use the CFX-9750, which is black and white and cheaper.

The only downside is that most colleges use the TI's, unfortunately. I liken it to most places using Microsoft when there are better alternatives out there (monopoly power). Anyway, a student who uses the Casio can do anything the TI-83 can do.
I'm a big fan, and my students seem to like it.

Works like a charm. Much easier to use than Texas. Comes with good manual.

The Casio fx-9750G PLUS is a great calculator for some things, terrible for others. Doing polynomial equations is simple, expecially when compared to a Texas Instruments' version. On the other hand, I have yet to figure out how to do a standard deviation. Keep in mind that if you're in high school, your course is almost definitely using a Texas - I can't tell you how many nights I've spent poring over the manual figuring out how to do the simplest of operations, while those with Texas Instruments know how to do it in a matter of minutes. If you're using it outside a formal math course in a situation that doesn't require too many complicated operations, it's a great calculator - I highly recommend. But if you're Pre-Calc or up, do yourself a favor and go grab a Texas.

This msg is posted on the 14 of June, 2005. Folks don't order this calculator if you need anytime before August 2005. I placed an order in end May, I am still waiting for the package. Late yesterday when I viewed my current orders, I noticed that the date when I am expected to receive this will be 5th of August 2005. Amazon still shows that the product will be shipped in 24 hours on its website.

I bought this version because it was cheap. It is very strong calculating machine compared to older generation but its lack of color and slow processing are great disadvantages. When you plot multiple graphs, the black and white display is a troubling. It is more so when you labor to spot the black tiny cursor on a black line. The slow processing is problematic during exam taking.

The other drawbacks are:
1- The manual is written backwards. You read instructions on how to enter data to find out that the notation would need more search to understand their meaning. The simplest thing such as turning on and off is cumbersome. The power key is colored like the rest of the keys, while the alpha key is colored in red. Turning the device off requires two keys, Shift + AC/on.

2- The F1-6 keys need longer time to relate what they do to the mode menu. I discovered their function by mere coincidence.

3- If you are looking for fast solution by using the index, you would not find terms such as exponent or factorials. It might take a whole day to learn how to get around these simple calculations.

4- Syntax errors appear on the display without any hint on the kind of error or on how to go back to previous step. You might have to experiment with the AC/on key or Exit key to get out of that.

This calculator does everything the TI-83+ does and more. (I was very hesitant about purchasing this calculator, because there were some features I had to have for class, but so far so good.) Unlike the TI-83+, the menu is very easy to use and understand.

This calculator is as good or better than my TI 83 plus for much less money. Full price this calculator is only 49.99. I found for even less elsewhere. The graphical icon menu makes it very user friendly without having to study the thick manual.
