Battery life: without a good battery, even the best graphing calculator might seem awkward. A graphing calculator needs a long-lasting battery to complement it. You can choose a calculator with rechargeable batteries, as you will not need to replace them at all times.

The 2nd and 3rd functions: scientific calculator buttons usually have more than one function. The COS button, for example, has the COS-1 function. You will have to push the shift button to be able to access the second function of a button. However, ensure the calculator does not have too many functions as this will make it confusing to use.

Price: getting a graphing calculator can be quite expensive, and its price varies depending on the ability to handle complicated tasks. However, you do not need to spend too much to get a good calculator. As a student, you do not need to invest so much, just check through the price chart and choose one that fits your budget. Getting highly expensive calculators can be for professionals like engineers and architects.

Processor/speed: the processor of a calculator determines how fast it will work. You can measure the processor of a calculator by the number of Megahertz it has. The faster you need your calculations to be, the faster the processor should be.

Conclusion

While this list is by no means an exhaustive list of top quality of the best graphing calculators for engineers you can find out there, the calculators featured here are still some of the best you can purchase especially if you will be doing some heavy calculations and graphing.

However, you should bear in mind that some of these highly functional programmable calculators are not allowed in certain exams, thus it will do you a lot of good if you can confirm first before purchasing especially if you are preparing for standardized tests like SAT, ACT, AP, etc. to make sure that your preferred choice is allowed for the exam.  But if you are looking for a calculator whether it’s for personal study or schoolwork or as a lecturer or professional engineer, then we highly recommend the  Texas Instruments TI Nspire CX II CAS graphing calculator as the overall best graphing calculator for engineers to buy.
