Casiofx-9750GII, Standard Graphing Calculator, White

When I first got this calculator, I had no idea what I was doing.So, I'll give you terms that went on in the classroom with the Texas Instruments that may be confusing to users of this calculator. This way you guys'll not be as behind as I was when I had to figure this stuff out by myself and with the book (which came in super helpful btw).GRAPHING-------------------------------------- When the teacher says "go to (press) Y= (Y equals)," what you really do is press the MENU button (it's grey and next to the big circle) then select GRAPH.- If the graph doesn't seem to work at all, or the line seems really funky, First go to GRAPH and then press DRAW. After that you should press F3 (View Window aka how much you want the graph to be able to see) and then F1 to go back to the initial view window (where something will probably be). Use the arrow keys to move around until you get a good view of it.- If you wanna see the entire picture because your calculator is zoomed in too much, first be in GRAPH mode and then DRAW. Then press F2 and choose AUTO. Note: this can sometimes be too much data to go through. Use the previous tip to set the window back to normal.- If you need to find the roots, it's all in the simple touch of some buttons!! After you DRAW your graph, press F5 and then ROOT. This will tell you where the roots, and zeros are. THIS IS A FEATURE OVER THE TI-86, where in the TI-86 you must actually look through the graph/table!!- If you need one of those "shading inequalities" graphed, simply go to the GRAPH setting. After that press F3, then F6 for more options, and then choose which one fits your problem.Not sure how to access the table next to the graph on the same screen yet, if anyone finds that out please comment so.OTHER STUFF-------------------------------------Switching Modes - If you ever need to switch modes, press the MENU button again. (Choose RUN.MAT for matrices (the MAT option in this mode) and basic calculations.)Need to set Calculator to Degree form - in RUN.MAT mode, press SHIFT and then the MENU button to SET UP. From there you may configure settings.Probability Terms - When you have to learn about probabilities, (in RUN.MAT) press the OPTN button (next to the SHIFT key), go to PROB and everything should be there.List Functions- When working with Lists, you must go to MENU then STAT. After entering your data into the first column you must go back to RUN.MAT and press SHIFT then (1) to put down "List."Type (1) into there for the first column, (2) for the second column, etc...If you were wanting to find the median (for example) of the list, simply press OPTN, select Med, then put down "List" and then press (1).Parenthesis - ALWAYS close parenthesis (()) when doing commands. Also when typing a negative number to a certain power, such as (-2)^7.History - To see previous equations in RUN.MAT mode you must press CLEAR twice. I have no idea why this is like that; maybe it's a feature to help focus on one problem.If you need ANY other tips on a [CERTAIN FUNCTION]/[CERTAIN MATH TERM], use the INDEX in the book!!! I remember trying to go through the pages for 40 minutes to find out a certain function when I remembered... indexes exist!! Lol... Also, DO NOT LOSE THE BOOK!!! It is extremely helpful and pretty easy to understand.BACK TO THE REVIEW-------------------------------------I will be sure to add more tips later on, however this is enough for a good start.I passed Algebra II A&B with this calculator with an "A-".Don't think that your kid or even *you* may not get an A just because of the choice of this calculator; I made a bunch of silly mistakes that had to do with my thinking and not the calculator itself.It has MORE features than the Texas Instruments for only half of the price!!Someone that I know who is taking college classes has a very fancy Texas Instruments calculator, and even then I heard him say "Yeah, I've got the conics app."With this calculator which is probably 1/3 the price of that one, the conics "app" is a standard feature!! There's no reason why to not like this thing for the price and value it offers!The batteries supplied with the calculator lasted me an entire school year, and I used it outside of math class as well.When it says "Batteries are low! Please replace" you've still got another 2 months or 3 with them lol, but I recommend the Amazon Basic batteries if you're going to need replacing.100% recommended - it does the job very nicely.(UPDATE) WARNING: If one is taking Calculus, there will be no nDer function for finding the derivative easily. One will have to know how to do these by hand...

I ordered this calculator for a probability and statistics course and was pleasantly surprisedto find it has all the main features of the more expensive TI brand.Important advice to students:1. Make sure you read the "technology" sectionafter each chapter of your statistics textbook if your class has a book that shows the stepsfor using a calculator. (Usually those are provided after the chapter content and eitherbefore or after steps are given for using other technology for solving problems with excelor statistics software.)2. Look for "how to" videos on YouTube using the name of the particular type of problem you'll be solving.For example: 2 Proportion Z-test3. Don't get discouraged if some of the steps look slightly different than the TI tutorials if no Casio instructions are foundbecause every time it counted, after the first couple of steps were the same you could then see exactly how to follow thesteps using your Casio because the only thing that was different was the particular name or location of the button on the calculatorand the same feature is available on yours using a different name or button in a different place, so you will be fine.I had read some of the other reviews on here before ordering mine and almost didn't order because a couple of them said their calculatorsdidn't last more than a month or some other short amount of time. However, mine has been working just fine all semester and most importantlywas there for me to use for the proctored exams when it really counted.If you're wondering if you will be alright with this one instead of the more expensive one or if you should just bite the bullet to avoid any chance of problems down the road, based on my own experience using this same Casio fx-9740GII Graphing Calculator, I'd buy this one again.I think you'll be pleasantly surprised (with just a little digging around online) with how many shortcuts for the formulas are possible with this one instead of having to do them manually. I know I was. I saved several hours once I realized there were tutorials online and in the textbook that reduced long formulas into just a few simple calculations.4. Take the time to really sit down and get familiar with your owner's manual. The extra minutes you spend doing this as well as looking at the names of the formulas and the names of the kinds of problems you'll be required to solve before you do each chapter will make finding shortcuts a breeze and save you hours of frustration and time from the very beginning of the semester.Statistics can be very enjoyable and rewarding as a challenge if you make sure you study and practice problems each day. Stayahead of your assignment schedule no matter what because it's one of those subjects where you must stay on top of it with each subsequent chapter building on the ones before it.Along with your textbook and your decision to spend at least a half hour every single day (without missing even one) to do your assignments, quizzes and tests, your Casio calculator could be your best friend all semester long for your Probability and Statistics class.

I bought this three years ago when my daughter's high school teacher said she needed a calculator. Money was (and remains) tight, and the reviews seemed to indicate that this would work. For the first two years, my daughter's needs weren't that significant, and frankly, almost any scientific calculator would have done the trick. But her final year of high school featured Honors Statistics, a course that the teacher told us, in no uncertain terms, was college-level in its difficulty.Our daughter was one of two folks in the class without a TI calculator. We thought this would be a problem, as the complex functions she was required to do could be even more difficult if she had to spend time figuring out how to do each one (and not being able to ask the teacher for help).She finished the year with an A in each of her four terms. She got an A+ on her mid-term and her final exams. By the second semester, her teacher had bought one of these suckers and was using it and recommending it to the department head. According to both of them, doing almost all of the functions is much simpler on the Casio.Folks, I suck at math. I can't tell you the differences between the graphs on the two devices or anything like that. But I can tell you that this got my daughter through a tough-as-nails course, and did it with about a tenth of the frustration the TI folks in the class felt (and at about half the cost). There may be something the more expensive device can do that this one can't, but it never came up during my daughter's time in high school.
