How to Choose the Best Graphing Calculator for Engineers

Choosing the best engineering calculator is much different than merely selecting a calculator to use for your regular math or science class. You will likely spend a lot of time using this device, and it will need to include critical features for making your calculator computations as simple as possible. The last thing you will want to do is have to spend too much time learning how to use your calculator as opposed to using it. That is where we come in. Use the tips below to learn how to determine if a specific calculator is for you and has the capability that you need.

Do I need a scientific calculator?

Within your curriculum, you will likely take an abundance of math and science classes within your beginning years of engineering. This will include courses like Physics and Calculus at multiple levels. A scientific calculator will come in handy in these courses. These are calculators that are designed to help solve problems like logarithms, exponents, and more.

Is this calculator durable, and will it last?

One thing that is important when looking for a calculator is durability and longevity. Chances are you don’t want to spend your money buying anew calculator each year. If you can find a calculator that will grow with you and can be used throughout your school career, this is an excellent option.

You also want to make sure that you have a durable calculator. Calculators now days can be as fragile as cell phones. They may require screen protectors or even protective casings to ensure that they will last. However, in some older model calculators, they are built to last, only needing a sliding casing.

How good is the calculator’s battery life?

Battery life is another make or break attribute for your calculator. Having to recharge or change the batteries in your calculator each month is unappealing. You want to ensure you have a calculator that can last for long periods.

Categories often have a variety of power sources. These sources can be solar power, traditional battery power, or rechargeable batteries. Having a calculator with a rechargeable battery is ideal, as you can simply charge it up and keep it running for an extended period.

Does the calculator possess Engineering Functions?

Engineering functions are another great option to look for when searching for a calculator. This includes an abundance of functions that will help you with graphing or problem-solving. Having a calculator, which is also programmable, is a significant benefit for engineering students. This allows them to add programs to their calculator and create their own programs and apps.

Can it be used on your Engineering Exams?

If you are an engineering student, taking the engineering exam is likely in your near future. If you want to refrain from buying two calculators, you will make sure that your calculator is not barred from by the Engineering council. You will want to find a calculator that will be allowed for the PE and EIT exam.

Does it meet your school’s calculator policy?

Your school’s calculator policy will also make or break the calculator which you can buy. Before purchasing a calculator, this should be heavily considered. You do not want to buy a calculator that you will not be able to use later. Make sure you look for any guidelines or rules concerning purchasing.

Is it extremely pricey?

Last but not least, price is another thing that must be taken into consideration. Price can be a significant deterrent when looking for a new calculator. Newer calculators can be a bit pricey based on the functions which they possess. Sometimes purchasing a calculator new may not be an option. You can try sites like eBay or Amazon if you are looking to find the best deals or a reasonable price.

With these tips in mind, you are sure to find the best graphing calculators for engineers. If you were struggling with where to start and what areas to consider, we hope this list was able to drastically help you figure it out. Having a calculator is an excellent tool for your journey into engineering. Having an engineering-specific calculator is a better option than using a 9th-grade graphing calculator.
