The best bargain in a graphics calculator,
This review is from: Casio fx-9750GII Graphing Calculator, White (Office Product)
Casio has been upgrading their graphics calculators for years. This most recent release of the 9750 model- the Casio fx 9750 GII-
is a huge break through in reasonably priced calculators. For starters, it costs about 50.00. It is now a mathematical subset of their more powerful 9860 models, typically priced from 80.00 to 100.00. All kinds of data, from statistical to programs to matrices can be transferred among the various models. The output is identical.
The screen is highly readable in all kinds of lighting situations. The unit is a bit smaller and more compact, but the keys are
easily used. I actually prefer the size of this calculator to any of my other Casio and TI models- including the Casio Slim. There is a complete range of statistical tests, intervals, and regression models. The conics graphs have been expanded greatly. Using complex numbers is easily accomplished.
For short, this is the best buy I have ever seen in graphics calculators. If it's your first, you can't go wrong. If you already have one ( or several) get one of these. It is really fantastic!
Be sure to compare this calculator to the newest Casio- the Casio Prizm.
Prizm FX-CG10 Color Graphing Calculator (Black)
You may ultimately want to invest in both of these fine calculators!

Does this calculator factor polynomials? If not which models do.

For symbolic factoring of polynomials, you might select a TI 89, TI NSpire CAS, or a Casio ClassPad 300, all of which are quite pricey.
To factor polynomials on the Casio 9750 GII, choose EQUA from the menu, select F2: Polynomial, and then choose degree, 2 through 6.
I chose 2, and entered coefficients 1, 2, and 1. The roots are reported as -1 X 2. Now have the students interpret the factors as
Also, the free software GeoGebra will factor and expand on virtually any computer.

Hello, Professor Holmes. I am wondering if you might know with which TI this Casio would be equivalent? My calc syllabus says we cannot have a TI 89 or above for exams, suggesting TI 83 or 84. I, of course, hesitate ordering because I don't want to wind up with an item I cannot use on exams. Thanks for your time and your informative post.

This casio is equivalent to the ti-83

it says on the box that this calculator does algebra and ive been searching like crazy online and trying to read in the book as to how to do it but no luck =/ so my question is can you really do algebra on this calculator? if so how?.
and also on a side note is there a percentage key on this calculator i cant for the life of me find it!

No percentage key as such- but check TVM for the really important problems involving loans and annual percentages.
This calculator doesn't do the algebra for you like some of the more advanced models do. But, if you look at the menu option EQUA, you will see that it can solve systems, solve equations, and solve polynomial equations. And by graphing, you can solve some really complicated equations. Just enter the left side in Y1, the right side in Y2, Draw, and G-solve, choose isct, and you can solve for x.
This is how calculators like this " do algebra ".

thank you for the reply i appreciate it, on a side note do you know of any graphing calculators that do do algebra for you along with having percent keys?
i bought this calculator and loved it for graphing but im looking for a superman calculator if you will so i never have to fear another test ever again =]

If there were such a calculator, it probably would be barred from test taking!
But you might look into an IPod Touch, with the 20.00 app, Space-Time. This app really
does algebra efficiently.
Most of the advanced calculators do not have a percentage key. But I'm sure that many of the
IPod apps do.

OH SO THE CONSPIRACY IS TRUE!!!! lol i cant use my ipod in class somehow teachers always think new technology is voodoo in terms of focusing in class. which is somewhat true. however i tried to do algebra the way you said and it worked but what about for problems that dont have 2 sides to it like x/5-1/2=6
In reply to an earlier post on Dec 8, 2010 5:14:27 PM PST
Hate to break it to you Grizzz, but the problem you just wrote DOES have two sides. And in reality, its much faster to learn to solve the problem you just wrote by hand than search for a calculator that will do it for you.
