In summary, when looking for a calculator for engineers, it is important to consider the specific needs of the user and the requirements set by their school or professors. While some may argue that graphing calculators are obsolete due to the availability of smartphones, there are still certain situations where a graphing calculator is necessary, such as during exams or in classes that only allow the use of calculators. For engineering students, a high-end graphing calculator with advanced mathematical functions, such as the TI-84 or TI-89, may be necessary. Other options include the HP 50G, HP Prime, TI-Nspire, and Casio ClassPAD, each with their own strengths and limitations. Ultimately, it is important to choose a calculator

Pick Best Calculator for Engineers.

Of course this Calculator needs to graph.
Buts also needs room for notes , and be able to scroll through old calculation.
Suggestions?

Why does it need to graph? IMO graphing calculators are a joke. Ancient technology with no useful purpose at all. I would suggest a laptop with mathematics software for things like graphing and notes. Otherwise, a cheap scientific calculator to do your arithmetic.

You say you want one for engineers, but I suspect you want one for engineering students... ?

By far the most common calculator I've see is the TI-84 and that is sufficent for most graphing needs as a laptop or phone is not practical or allowed for all uses. However, TI-84 only provides decimal answers, for exact answers a TI-89 would be better. The TI-89 has more features than the TI-84 and takes a while to learn but the added functionality is worth it. TI and Casio graphing calculators only have the first quadrant trig functions, if you need all the trig functions, HP calculators have the full list.

Smart phones have just about made graphing calculators obsolete.

I don't completely agree. In schools there is a big difference between allowing students to use a calculator and allowing them to use a phone.

As I read your requirements, you want a recommendation for a graphing calculator for an engineer (or engineering student). An ME, EE or Physics student could actually require a calculator that can support all types of high end math. A Ti 83/84 falls far short of this requirement (although many have used this calculator to graduate as it functions as a decent scientific with a great set of statistical functions, something that is very handy for labs and business majors). And if your professors/school allows a high end graphing calculators with CAS, the following five calculators leave everything else in the dust. I will list them in order of power/features. This order could change as the Ti-Nspire (probably very little left to develop as it has been on the market for nearly a decade) and Hp Prime built in functions are still being developed.
.
1st, Hp 50G, 2nd, Ti-89, 3rd, Hp Prime, 4th, Ti-Nspire and 5th, Casio ClassPAD.
.
Does this mean you should automatically buy the Hp 50G (and won't be available for much longer)? But it is an RPN/algebraic selectable calculator and if you use it in algebraic mode, the Ti-89 is actually the superior calculator (Hp 50G has bugs in Algebraic or poorly implemented units conversions and other issues when Hp crammed in algebraic support into this line). Both of these calculators are NOT being marketed as both Ti and Hp now push their Nspire and Prime calculators as their high end solutions.
.
The Ti-89 is superior to the Hp Prime for many high end math features too. The Hp Prime actually evolved from the Hp 39/40G line of calculators and has several design limitations (single letter variables) that will always make it less useful compared to the Hp 50G or Ti-89.
.
The Ti-Nspire is a locked down programming system (to keep cheat sheets from being loaded on and make it more test compliant) as such is also crippled even further than the Hp Prime.
.
The ClassPad evolved from the Casio FX 1 and FX 2 CAS line and as such have similar limitations to the Hp Prime. However, the last three have color screens which could clarify differences in graphs when displaying different functions on the same screen.
.
My own opinion is that any of these is a bargain to have in your backpack to help with high end math. And where the professors allow these calculators in their class, you might be foolish to use anything less. However, if you're not allowed to use these during exams or quizzes, these then become teaching aids and you might be better off using Math software which can be used in reports and getting an NCEES compliant calculator for your personal use.

What features should I look for in the best calculator for engineers?

When choosing a calculator for engineers, it is important to consider features such as the ability to perform complex mathematical functions, handle both decimal and hexadecimal calculations, and have a large and easy-to-read display. Additionally, look for a calculator with programmable functions, conversion capabilities, and a durable design for long-term use.

2.

Can I use a regular calculator for engineering purposes?

While a regular calculator may be suitable for basic calculations, it may not have the specialized functions and capabilities that are necessary for engineering tasks. A calculator specifically designed for engineers will have features such as trigonometric functions, unit conversions, and the ability to handle large and complex equations.

3.

Are there specific brands that are known for producing the best calculators for engineers?

There are several reputable brands that are known for producing high-quality calculators specifically for engineers, such as Texas Instruments, Casio, and HP. It is important to do your research and read reviews to determine which brand and model best suits your needs.

4.

Is it worth investing in a high-end calculator for engineering purposes?

It depends on your individual needs and preferences. If you will be using the calculator frequently for advanced calculations, it may be worth investing in a higher-end model that has more features and capabilities. However, if you only need a calculator for basic engineering tasks, a more affordable option may suffice.

5.

Can I use a calculator app on my phone for engineering calculations?

While there are many calculator apps available for download, they may not have all the necessary features and functions that a specialized calculator for engineers would have. Additionally, relying on a phone app for important engineering tasks may not be as reliable as using a dedicated calculator. It is recommended to use a physical calculator for engineering purposes.
