Casio Graphics Calculator FX-9750GII

*****DISCLAIMER TO FUTURE/CURRENT BUYERS***** Everyone who is thinking about purchasing this calculator it is an EXCELLENT and POWERFUL instrument that would aid you in studies, programming or other general uses however please note that this calculation DOES NOT HAVE NATURAL DISPLAY SETTINGS, Natural display settings are settings that allow you to keep equations in their basic forms e.g. 1/3 would be converted to 0.333333333 or surds would come up as decimal.If you want a calculator with these setting then you must purchase the FX-9860GII: Casio FX9860GII - CASIO FX9860GII GRAPHIC CALCULATOR This is not stated within the item description so I wish for this to be resolved. Regardless of this minor issue I decided to give this 5* because it truly is a fantastic calculator and if you don't mind that this calculator isn't natural display then this calculator is cheap and convenient.

I bought this calculator for my A levels. It's incredibly useful, especially in C2 and C3, and helped me tremendously. I used it mainly for drawing graphs and checking my answers for differentiation/integration questions. It also allows you to solve equations in seconds saving valuable time in exams. The only problem is that it has the old style display format, so you don't get exact answers. This is problematic, as it becomes very difficult to enter complicated functions involving fractions and irrational numbers. However, this can be overcome by upgrading the OS. Although this sounds complicated, it's actually very easy and takes a couple of minutes. There are multiple video guides on how to achieve this on Youtube and plenty of tutorials on the internet.

Bought this for my son who gave his (same model) a shower from his water bottle at the gym; drying out did not revive it. An all this just a month before his exams, when it wouldn't have mattered in the same way. So had litttle option but to buy the same as he was used to. I don't use this but have used calcs since the Sinclair Cambridge and HP29 (brill!); I'm told it works fine, and it appears up to usual Casio standard. My personal view is I'm over a barrel because it's a school spec graphics calc, and price seems to be held high, for what it actually offers. The school has to loan out these units to people who can't buy it, and I'm not surprised, at two ponies or bullseye! Blimey! I know it's more useful than a phone(!), but.... I ha[ppen to have an advert for the Sinclair, something like £17 in kit form in 1974. And the HP was astronomical (a months pay), when I was free, - and daft. In Staples now, I spotted a simple four-function calculator for £2.20 that hooks into a ring binder. In real terms then, I suppose we've been spoiled by the technology being jacked up, and the price lowering, of these things. However, I tend to think that this unit single-mindedly bucks that trend, and is really being overvalued because so many schools tote it as 'the required equipment'. I'd better hang up my sliderule now! Wish kids (teachers?) would learn on generic scientific calculators, a tenner, job done!

The postage is outstanding, with the quality of the calculator being in a great state. This calculator is amazing for A level Mathematics and beyond; it's very easy to use and helps a lot. The only improvement I would suggest is that the box is huge when it arrives, especially in comparison to the size of the calculator. It could be a lot smaller, but if it's that big for maintenance reasons then that's understandable.

This calculator is one of my best purchases. It is robust and works in a very understandable way, once you get used to it. It is permitted to be used for A-Level maths in the UK, which is only one of the many uses I have for it. It is very easy to upgrade the software to the next model up, which gives tons of extra features (without these the calculator is less appealing, due to the lack of maths display)

This was the cheapest Casio graphics calculator that I could find and there isn't anything that I feel it needs to be better than the £100+ graphics calculators. The graphs are easy to plot and interpret, and the integration calculations are excellent too. There is still so much I haven't yet learnt to do on it and I am still very impressed regardless. The only cons that I have are that it is not a very good standard calculator - there is no fractions button like there is on the scientific Casio calculators, and it doesn't leave answers in terms of pi. But this is fully compensated by the fact you can take more than one calculator into the exam! I found this very useful for Core 3 and Core 4 of OCR A Level maths.

Really great calculator. I frequently use it for A Level Maths and Further Maths and it is invaluable to my studies. It has the ability to find inverses of matrices (as well as basic addition/subtraction/multiplication) so is great for exam checking. The graphing function (whilst it can be a little buggy with zooming) is great for checking the shape of a function or even reading off values thanks to the 'trace' command. As well as having a financial mode, conic mode and many more it also allows you to write your own programs which I find very useful and time-saving. For example, I've written programs to find the roots of quadratics/cubics etc. in order to speed up factorising. Would definitely recommend. One thing to consider is the lack of natural display. Very annoying at some points. Especially when you receive a seemingly random decimal answer which is, in fact, 'Pi / 6' or 'Root 3 / 2'. But I use a cheaper Casio to check answers in those situations.

This calculator was very useful during my GCSE Mathematics exams and will without a doubt be useful for A Level Maths in September. The product is a little pricey and the menus take time to get used to especially if you are used to the Casio 85ES and therefore it may seem quite confusing at first. However, after some practice and reading through the booklet, the product is bound to aid you in your exams. Pros: > Handles very complex calculations with ease > Has very good battery life > Is easy to use once you get the feel for it Cons: > Quite heavy > A little expensive > Takes some getting used to

j'ai choisi cette calculatrice pour ma femme qui a repris une formation diplômante les +: très esthétique, patins anti dérapant efficaces, nombreuses fonctions... les - : prise en main délicates pour personne non connaisseuse mais manuel en français très détaillé je recommande cette calculatrice si vous êtes dans le parcours scolaire du collège au lycée et même au delà

Dieser Taschenrechner hat mich nun schon durch einige Klausuren in meinem Studium begleitet :) ich bin sehr zufrieden mit ihm! Anfangs war ich mit dem System total überfordert, da ich zuvor noch nie einen Tr von Casio hatte. Aber hab mich da schnell reingearbeitet. Für die höhere Mathematik auch absolut geeignet. Er kann sogar noch viel mehr, was ich alles nicht so brauche. Trotzdem guter Taschenrechner, der mir immer Glück gebracht hat 😊

Il suo display monocromatico ad alto contrasto è piuttosto ampio con 8 righe contenenti 21 caratteri ciascuna. Purtroppo questo modello non è provvisto di retro illuminazione come ad esmpio la CASIO FX-9860GII . Non è molto ingombrante e sta comodamente in un piccolo zaino 21,3 x 87,5 x 180,5 mm è dotata di un coperchio che protegge la tastiera da urti indesiderati quando non la utilizziamo. Funziona con 4 batterie ministilo e pesa circa 205gr con le batterie alloggiate. La durata delle pile è di circa 300 ore (visualizzazione continua del menu principale) e di 230 ore di funzionamento continuo (5 minuti di calcolo, 55 minuti di visualizzazione); 1 anno se inutilizzata e spenta. Questa Casio fa un po' tutto, risolve equazioni con funzioni di integrale, differenziali e fa il calcolo di probabilità. E' ottima per i calcoli di matematica finanziaria ecc. Ognuno immagino la compri per un utilizzo particolare e relativo ai propri studi o prefessione. E' dotata anche di porta usb per il trasferimento dei dati. 61 KB di memoria sono sufficienti per memorizzare molti programmi utili durante i nostri calcoli. Consigliata.

Calculadora muy potente, puede resolver grandes sistemas lineales por el método de la matriz inversa. Hace todo muy rápido. Si eres un geek, te gusta la programación, las matemáticas y la ciencia es perfecta, si no te gusta programar, vete mejor a por una Casio fx-991 SP X, que es mucho más intuitiva. No tiene entrada natural, pero no es un gran problema. El resolvedor de ecuaciones es de lo mejor, me es muy util para química, (equilibrio, cinética...), en cambio no es cierto eso de que resuelve ecuaciones de hasta sexto grado (polinómicas), sólo hasta segundo grado, de más grado, solo te da una de las soluciones y encima aproximada, pues lo hace por el método de newton. Pero lo mejor es su lenguaje de programación, he probado muchos lenguajes, y el Casio Basic es el mejor, es intuitivo, fácil y divertido de programar. Luego está un poco obsoleta, la pantalla tiene poca resolución, deberían de sacar un modelo nuevo. A parte está muy bien construida, es dura como una piedra.

Buena compra, el paquete viene integro... recomendado al 100... una perfecta graficadora a un precio muy muy accesible
