![]() Consider this problem from my old circuits book: Find Equivalent impedance R1=2, R2=3, R3=6, C1=-j2, L1=j4 _R1_ │ │ │ │ R2 R3 │ │ │ │ C1 L1 │ │ _│_│ Zeq= 2+ 1/(1/(3-j2)+1/(6+j4)) This crashes the fx-991(in complex mode) but is done easily on the HP35s in either RPN or ALG mode. I might do a full comparison one day but after working a few problems, I was surprised to find the fx-991 crashes when doing fairly simple problems with complex numbers. However, it is nice to have two calculators so after watching Dave oogle over the fx-991 I bought that as well. It which seems to have the same firmware as the 35s that I recently bought. So which is the best? When I took the Mechanical PE exam in '07 I used the HP33s but I loaned it out and never got it back. There are a few posts online but they really lack any substance, mostly just comparing the calculator specs. Source: I want to use the best one on the PE exam and then recommend to other PE hopefuls. Find exam delivery materials for the exam diet, includes scaling calculator, sound operator instructions, change of timetable, alternative venue forms. Casio: All fx-115 and fx-991 models (Any Casio calculator must have “fx-115” or “fx-991” in its model name.) Hewlett Packard: The HP 33s and HP 35s models, but no others Texas Instruments: All TI-30X and TI-36X models (Any Texas Instruments calculator must have “TI-30X” or “TI-36X” in its model name.).However, the only a few simple calculators are allowed on the PE exam: I sent it into Dave for EEVblog #715 - Mailbag ) I recently bought a "TI Nspire cx CAS" which I am still getting used to. When I was working on a bachelors degree, I used a "TI Voyage 200" which died a few years ago. Its a big challenge that I may never finish but eh. It's pretty outdated now and am looking to upgrade, but what's best from my degree in EE and applied math I was looking at the TI-84 Plus CE Python, TI-Nspire CX II, and TI-Nspire CX II CAS. I work for a power company and have been bored at work lately so I'm thinking I may study up and take the PE exam in Electrical Engineering. Best calculator for EE and applied math I'm finally retiring my TI-84 Plus Silver Edition from 2011 which got me through high school and my 1st degree. Michael Fine at the University of Pittsburgh. He was previously a full-time clinician at the University of Lausanne in Switzerland and completed the intensive Clinical Research Training Program (CRTP) under the direction of Dr. ![]() In this post, you’ll learn: Which calculator brands are allowed by the NCEES. ![]() I earned a Professional Engineer (PE) license in Mechanical Engineering in the USA through a combination of education, experience and passing of an 8 hr exam. Drahomir Aujesky, MD, MS, is an active clinician-investigator who predominantly researches venous thromboembolism. We’re going to go over PE exam calculators. I have several EE's in the family and I have even taken a few college level EE courses. First Post here! Which is the best calculator for the PE exam? I'm a mechanical engineer but always had an appreciation for electronics. ![]()
