Graphing Calculators

Calculators have been around for quite some time and it is easy to find why because apparently there is only so much our brain can process at once and complex math is not something that the general population is capable of. Of course you see geniuses from time to time but most of us are not and this is why humans invent to help them on a daily basis. Telephones for example were created as a communication tool but now evolve into something more useful and versatile.

Calculators are the same but they aren’t really useful outside of calculation itself. The tool started as a very simple machine that can add, subtract, multiply, and divide but today you can find them that can draw or even play simple games. The most capable calculators are graphing calculators and this is why they are expensive. There are so many of them and most of the time people choose something like Casio FX-CG500 Vs FX-CP400 but there are more than plenty of alternatives.

In general the graphing calculators are those that have an ability to display plotted graphs for complex equations such as parabolas and other plotted results. They are also more sophisticated than typical calculators because they can process multiple calculations and perform complex functions. They first appeared in the 1980s and replaced basic calculators for other functions as well as becoming a tool in classes of higher education. However, not everyone will need a graphing calculator because we can still use other calculators to perform basic math.

Chances are students will need a graphing calculator and the teacher or professor will recommend or tell them to use one in class. The most useful case is when learning algebra since it is good to have one when studying the subject even though it is rarely required in the first-year. Algebra can be done without one but by using it we can help reinforce the concept so in the second year we can already master how to use this tool for other purposes like sequence graphing tables, as well as understanding the creation of a matrix.

Not only math, graphing calculators can be useful in real-life applications such as when working on financial math. We can use them for mapping out a quantity of data to figure things out like sales. We can use them to generate statistical models or see the information in the form of graphs and figures so having a graphing calculator around will be very handy. However, just like any tool, the option for everyone who will want a graphing calculator can vary.

About Casio FX-9860GII and FX-9750GII

Just like most products, the more you pay the more the product can offer and for a graphing calculator we don’t need to spend too much on something that we won’t be using. Do consider what you will want to use them for and match the options with the unit. For students, we can ask the professor or teacher about the calculator they recommend for the class so we can just get the model they prefer. In addition, you can just select one from any popular brand.

We say popular brands to make sure that we can find the tutorial or tips when using one because more users means more people who can help us as well. Besides the famous Texas Instruments with its popular TI-84 Plus calculator, Casio also makes a wide range of options on the budget section. This Japanese brand is not lacking at all and depending on what you will need, there are more than plenty to choose from their collection including for budget options.

For those who want to invest for something that will be useful from high school to college, the Casio FX-9860GII and FX-9750GII will be two options to consider. These calculators are very useful and come with all the basic functions while being helpful for a wide range of subjects. The two are also easy to understand and our favorite thing about Casio’s calculators is they have an easy to understand menu that makes the tool beginners friendly, moreover the two are very affordable.

In comparison, as you can guess the 9860GII is a higher model and this calculator will bring more too, with an additional price tag. However, you can convert the 9750GII into the higher option by flashing it to have a different operating system yet, this is not something that everyone can conveniently do at home so it is better to go with 9860GII if you will need the additional features it can offer. Regardless of the option, we love these calculators for the ease of use and price point.

Casio FX-9860GII and FX-9750GII Design

Before getting into what Casio FX-9860GII and FX-9750GII can offer, first let’s get into the unit and its physical quality. As you can see, the two are similar but with noticeable differences and it is about the display size with 9860GII being slightly wider. They seem to have the same resolution however which is not bad but can be much better. If you have used Casio graphing calculators before, their layout will be the same and side by side the two are almost identical.

The housing is made of robust plastic with easy to press buttons and clear labelling. The tool is powered with 4 AA batteries and sadly none have solar panels as well but worry not since the battery can last very long, in fact you will be changing it very rarely. The display quality is decent and you can see the graph of information clearly as well but we doubt they will be easy to read when getting into details.

Casio FX-9860GII and FX-9750GII Interface

Now for the most important part, let’s see what the Casio FX-9860GII and FX-9750GII can offer and we want to start with one of the most popular features in graphing calculators which is CAS which sadly none of the two have. However, they have a clean interface and we like how they are easy to understand, at least compared to TI 84 Plus which is another extremely popular graphing calculator so if you want to start right away, we do think any of the two will be great.

The buttons are laid out logically and the main menu is easy to use but the screen of the 9750GII is not in contrast and depending on your eyes, it does look washed out so for people with glasses 9860GII will look significantly better. What we are not very fond of about Casio’s interface is their small menus at the bottom of the display because we find it hard to read. In addition, only the 9860GII comes with a natural display, meaning it shows results and calculations like in textbooks.

Casio FX-9860GII and FX-9750GII for Graphing

Because the Casio FX-9860GII and FX-9750GII are graphing calculators, you will need to know how to graph with these tools and they are in fact the same. Very straightforward since all you need is choose the graphing app, enter the functions in a list then just press draw or F6. The calculator will show the graph right away and then we can calculate the intersects, maximums, and minimums from the picture. The ability is the same and since the resolution is low, it will be challenging to read it when you have multiple functions graphed. 

Casio FX-9860GII and FX-9750GII Apps

Lastly for the apps, these calculators are also coming with all the basic functions that you can find on many other similar graphing calculators but since the 9860GII is a higher model, this version is also coming with more or a total of 17 apps instead of 14. Some of them are graphing, conics, equations, programming, recursion, and app for finance. On the other hand 9750GII is lacking in some such as unit conversion but they are equally useful for typical math applications.

Casio FX-9860GII Vs FX-9750GII

Both Casio FX-9860GII and FX-9750GII are good calculators that will be ideal for students in higher education and chances are they will last for a very long time. The differences are not major and we do think they are very similar. However, the 9860GII will give you a better experience as it comes with a better and natural display too. It is necessary to get something you are comfortable using and this calculator is slightly better. It has some more apps too, if you need more than just the basics they can offer.
