Integrals are a tough part of any mathematics curriculum.

One of the defining pillars of Calculus, integration is key to understanding how infinitesimal data work in describing displacement, area, or volume.

All of this isn’t easy work and to accomplish this without a calculator can be tough. It’s not impossible, of course, but any integration calculator can help you solve equations faster, and without the legwork that normally is needed.

The basis of integrals is assigning numbers to functions that can provide deeper information on said data. What better tool to use for solving functions that an integration calculator?

These are powerhouse portable devices that can give you an edge within any day-to-day operations, or within a school setting. Instead of being built as a finite device, most of the calculators can be expanded on, or changed, by adding your own programs to solve equations. This gives you control over what material you need to be covered, and what needs to be included on your device.

Having trouble deciding on where and what calculator to buy? Don’t worry, we have you covered.

**Defining the Basics Behind Any Integration Calculator**

You might be asking yourself, “what exactly is an integration calculator?”

Well, it’s not any specific brand or special model of a device. No, most of these types of calculators simply can process and run __Calculus-based programs__ or functions.

Most of the time, you’d use hardware that can run these types of equations on problems that you cannot do by hand. Or, rather, that you could do, but it would be extremely time-consuming to do so. There would be no point in trying to solve those types of problems, and thus the integration calculator will be your best bet.

Integrations calculators often have different under-the-hood components than your standard problem-solver. You’ll find that these premium devices include more user-available memory for quicker calculations, a faster, more reliable processor, and support __upgradable flash ROM memory__.

The faster the processor the quicker the overall computations happen, saving you time. The memory available for you, the user, is important because that factor determines the number of equations or programs you can save for quick-access to.

The overall quality of the display also is a factor in determining a good integration calculator. The calculators found below come in a variety of sizes. Each screen is a little different than the other, with some featuring color screens, larger screens, or higher-resolution screens.

Everything boils into a price, though. Every little feature, from the color display to the intuitive design, has been factored into the standard price of the device. Some of the better calculators may only cost $100 upfront, while others start out at over $200. You’ll always have to consider the best hardware for your needs, so always keeping the price in mind can help you choose.

**Top Places to Buy Integration Calculators**

Some of the best places to buy integration calculators are Amazon, Staples, or eBay. Plus, local listing sites like Craigslist or Facebook Marketplace can also be great starting points.

The one issue with buying a new integration calculator is the price. These premium devices don’t go on sale too often, forcing you to pay full price to acquire its services.

So, if you’re wanting a brand-new electronic device, Amazon or Staples are good options. If something isn’t right from the start, or you find out a piece is missing, you’re in luck.

These retailers are good about replacing or exchanging a device that wasn’t as described or doesn’t function. You won’t want an expensive device to quickly become a paperweight.

Ideally, you can also test out different calculators this way. It might seem weird, to buy a couple of integration calculators to try out. The reality is you can see which one fits your preference and uses better.

After running through samples of problems or seeing what you can program the calculator to do. All you must do is return the ones you didn’t favor. This way, you’re getting the perfect one for you, taking some of the guesswork out of it.

Going used is a great way to save some money. Most of the time the calculators found are still in great shape.

Ultimately, the choice is up to you.

**Functions and Programs Available on an Integration Calculator**

The point of the device is to help you with solving higher-based problems. The device you choose must be able to provide the specific commands to do so. Functions are the backbone of Calculus. So it’s understandable that the calculator you’ll need to solve them can recreate and run through the answers.

Some of the most popular inputs you’ll want to see are __derivatives of a function__. Differentiation equations, and limits and infinity. There are more, of course, such as velocity, limits, and antiderivatives.

All of these, believe it or not, require a different set of programs within the calculator. This means that any old calculator won’t be able to run through them. Which is where the integration calculator comes into play.

**Our Picks for Recommendations of Calculators**

Of course, knowing all this information doesn’t do you any good without having any devices to look at. There are plenty of different manufacturers that create entries into the integration calculator world. Knowing the best from the rest can pay dividends long-term.

**Texas Instrument’s Selection of Calculators **

You may be familiar with Texas Instruments, the long-time conductor manufacturer. Who is also responsible for creating the first handheld calculator. They offer an extensive line of graphing calculators, which is another title for functions. Most of the graphing that can be accomplished with one of their high-end calculators

Their whole graphing line, which includes the TI-83 Plus, __TI-84 Plus__, TI-89 Titanium, and TI-Nspire CX is all going to work great for integration purposes. The lower-end TI-83 and TI-84 models aren’t going to have as diverse of possibilities. With the TI-Nspire including full computer software and 100MB of usable memory but will work almost the same. The biggest difference is going to come in now the calculator performs, and what it can do.

Using the TI-Nspire CX will come as a shock to most, as the device has an interactive and intuitive display. While a lot of older calculators feel like programmable bricks that can solve complicated problems. The newer Nspire has features that make the use simpler.

However, if you’re thinking the entry-level calculators will suffice. You’ll be happy to know that all feature the standard functions you’d use daily in mathematics. This includes finding derivatives, graphing limits, and going through differential equations.

In the end, it’s hard to not recommend a Texas Instruments device. The company knows how to make a solid product, as is evident from its almost universally-standard implementation.

**The Smaller Manufacturers in the Calculator Game**

If you’re looking to be bold or stray away from the company with the biggest market share. In the calculator shop you have options.

Companies like HP or Casio provide their own version of graphing calculators. That will work the same as any of Texas Instruments’ machines. Also provide a unique edge in software, and quality of product giving a better overall bang for your buck.

HP’s offering comes in the form of its __Prime Graphing Calculator__. Using a touch display, rich text, 256MB of ROM memory, and a 400Mhz ARM9 processor. This provides more than enough quality to be considered as a top-level contender. Similarly, Casio’s own __ClassPad fx-CP400__ provides a huge color touch display, 24MB of flash memory. And most of the right tools necessary. Both retail for just $150.

The HP is a better pick to compete with Texas Instruments devices. But the biggest drawback going with a smaller-known company comes down to use. Specifically, with the way information is presented to you. Thus, directions given regarding the calculator’s use will be tailored to the Texas Instruments models.

Not the end of the world, but something to consider.

**Buying an Integration Calculator isn’t So Bad**

You find a premium calculator like Casio HL-820V, Casio MS-80B, Casio FX CG10 PRIZM, Casio fx 260. For a new mathematics class or another curriculum, it sounds like a tall order. You’ll need an advanced calculator for most classes in higher-level math, so finding the right one is important.

There are plenty of different things to consider when buying an integration calculator for your needs. But one of the most important is where you buy the machine. Even though you can easily find these mini-computers at retailers like Amazon or Target. You can consider getting them used. Both options offer something different when buying.

At the end of the day, having the right integration calculator is just as crucial as understanding the material. You may also check our 7 Best Calculators for Statistics You Can Rely.
