Feb 17, 2012 · The HP 15C is less than $100, and it was THE killer scientific calculator for engineers and chemists back in the '80s. Fits in a shirt pocket and does everything its larger predecessors did. I'm tempted to order one.
Hp-15c Gone, but not forgotten - Physics Forums
Feb 18, 2010 · HP has a 15c emulator for the iPhone. It is either $29 or $39, but that is way cheaper than what they go for on ebay. I'd buy more than one 15c, 32sII or 42S if they were ever reintroduced.
Need an on-line calculator for a simple calculation - Physics Forums
Jan 14, 2025 · This is a simple question, but after 30 minutes on Google, no sensible results. I want to solve this equation: 1/(2.04Sin(29.36 + 0)) on a regular basis. My idea was to have that term as a Google search, saved as a bookmark. The idea has worked well for years for another formula, but without...
RPN vs Algebraic Mode on calculators. - Physics Forums
Feb 24, 2007 · RPN rules. When you have become familiar with that notation, you will zip through calculations that used to seem tedious. I got my first HP back in '76 or so, when I went back to college to take some courses that related to my jobs in soils testing, materials inspection, etc.
Which calculator? Hp 50G vs Ti89 Titanium - Physics Forums
Oct 11, 2006 · I remember not being able to financially justify trading up to an HP 15C, since my 29C did everything I needed, but I really liked the 15C. It's financial cousin, the HP 12C is still quite commonly seen in banks, real estate offices, investment counselors' offices, etc.
How do I calculate roots with the 15c - Physics Forums
May 12, 2012 · I'm trying to calculate the cube root of -8, for example, so I type in these buttons: 8 CHS (change sign) Enter 3 1/x y^x But it gives me an...
Goodbye TI-85, Hello HP 50g: A Calculator Review - Physics Forums
Sep 26, 2012 · I thought of the TI-89 Titanium. But then I remembered that HP had a good line of calculators - at least they did. I do not think they have maintained their quality quite so well as they used; but their latest offering, the 50g, was quite impressive. What turned the tide for me to switch from TI to HP was the Daniel Doherty review on Amazon. I ...
Calculating required horsepower - Physics Forums
Sep 15, 2019 · My attempt at the solution goes as follows: power = work / time power = (distance * force) / time power = (2640 ft * 2000 lb) / 6 seconds = 880000 ft lb / sec horsepower = 880000 ft lb/sec / 550 ft lb/sec = 1600 hp however i do not know if this is correct
Ansoft Maxwell, "cannot apply Current Excitation to non planar …
Mar 29, 2012 · Hello I am new with Maxwell. I made a motor drawing in solidworks and imported it in maxwell. I found some tutorials, and searched on the internet but could not find answer to my problem. So when i try to assign Excitation Current to an coil i get the message Excitation 'Current1' : Cannot...
Question about parallel plate stuff - Physics Forums
May 21, 2016 · Question : If released from the inner wall, what would be the kinetic energy of a 7 fC charge at the outer wall? 1fC = 10^−15C. Homework Equations KE = q*Delta(v) The Attempt at a Solution I have solved each of the other parts of this question. I found that Delta V was 1×10^−2V. The question states that 1fC is 10^-15 C.
