If I could have only one this would be it. Beautiful keyboard, they had some criticism that it was too stiff in early models but now it is great. Matrix handling is good (and finding a matrix solution is quicker than on the Prime) and it does basics like polar-rectangular quickly and easily. Swissmicros DM42 is probably the perfect calculator in everything except the display of complex calculations, you need to really get your head around RPN entry and the stack.
#Mechanical engineering calculator windows
I don't like the keyboard or that the UI looks like Windows or that there aren't more keys for basic operations, or that the numerics sit above the alpha keys, or that they chose ABCDE over QWERTY.Ĭasio is cheap and competent (and solar!). First thing I did was put a screen protector on it as a lot of people say the plastic is very soft and will scratch if you drop a pen on it. You can backtrack through calculations and edit your expressions. Sounds like a lot of negatives but I am definitely not sorry I bought it. Answer: Casio fx 115ES Engineering Scientific Calculator This Casio is a great calculator for everyday usage. The keyboard is good but not as perfect as classic HP calculators. The battery doesn't really last a long time so it needs to be charged reasonably often. Its screen is also a bit blurry with some antialiasing going on but the screen isn't high enough resolution to make that work, the result is that the edges of text are blurry. The Prime shows everything on-screen so you can verify entry before looking for a final result. Of the four I always reach for the Prime.
#Mechanical engineering calculator plus
I have HP Prime (G2), TI nspire CX CAS (gen 1), Casio fx-991ES Plus and a Swissmicros DM42. If it's out of your budget to get both a graphing calculator and a scientific calculator, then consider waiting and saving up for the scientific calculator in the future when you have to actually take the exam the HP Prime will do everything you need in the meantime. engineers get an HP-35s for this reason, although there are plenty of cheaper alternatives, like the Casio fx-991EX and the TI-36X Pro. Therefore, you should also plan to own the relevant scientific calculator. You should research the specific requirements of the licensing or credentialing exams in your chosen field, but I would guess that they don't allow graphing calculators anyway. (I also own a TI Nspire CX CAS, a NumWorks, and over a dozen other graphing, business, and scientific calculators.) In fact, I recommend the HP Prime in general as the most all-around useful handheld calculator. I would strongly recommend the HP Prime over the TI options, especially if your curriculum doesn't require TI calculators.
