Is there a single key calculation for the reciprocal of a number on a typical
scientific calculator?

Is there some symbol besides "1/x" to look for?

Thanks.

I wonder if there is a psychoanalytical name for people who cannot speak
to others without insulting them at the same time. With some people, like
Bozo, it's obtuse...

Usually. On mine "1/x" is next to sin, cos, tan.

InverseTrig "1/x" is cuberoot!

divide = =

Will get you a functional equivalent for a single number.

My first calc was an HP35 ($400 at the time, the cost of a Honda S90
motorcycle) so I'm a RPN slave. I buy old 32S2's now.

I need a good HP emulator for my Samsung phone. Any recommendations?

On my Casio fx-82TL
x-1

or
enter number
type =
then type 1/Ans (Ans is a key)

Amazing, had not used that calicalucilator for years..
miracle the battery still works
All screwed closed, no idea what I put in there,
see on the screws I had it open...
Curiosity awakened, opened it
Panasonic alkaline battery, still at 1.35 V :-)
Casio makes some good stuff, have a radio watch from them too

But you cannot cut and paste from a calculator
so I use wcalc in Linux:
~ # wcalc
Enter an expression to evaluate, q to quit, or ? for help:
-> x=100
x = 100
-> x^-1
= 0.01

Looks nice. I'll try it. Thanks.

It sort of looks like an old HP9100 desktop, the daddy of the HP35.

Enter 1 then divide then the number then equals.

Otherwise, single key IS the "1/x" key.
You really are getting senile.

I use Go41C now. In the Android store.

The cell phone with the app open looks like a glowing
HP41 in the dark. It gave a surreal impression to the
man who supervised my diploma thesis. We still meet
from time to time in a local pub. He was an early
adoptor. He is 85++ now. The numbers start to be
discomforting.

And on Windows: Warren Furlow's HP-41CX, or is it V41 officially? Perfect.

I bought my HP-35 when I was still at school. The father of
a classmate who worked for Brown, Boverie & Comp ordered them
for us. At this time, HP had not yet an end customer operation.
It was still in the HP test equipment section.
I still have it, as well as my HP-41C. They both would probably
work with new batteries.

Cheers, Gerhard

You can get one for your PC too.

You can even DL an Enigma machine and send coded messages between
two parties.

Unless one is using an HP RPN calculator, then the keystrokes are:

1 [enter] number [divide]

Most have a 1/x key.

What resistor to put across 1K to get 400 ohms?

400
1/x
1000
1/x
- 1/x

I have an HP11C and several HP32S calculators and they have
the reciprocal "1/x" key.

I hardly use them anymore though. These days, I most often
use something that resembles Unix's "dc" calculator, but
better adapted to scientific/engineering work, and which I
wrote myself. Its unique (I believe) feature is that it
can understand and print numbers with metric prefixes. So,
say, 1.2e-7 is the same as 120n.

I use a new 35s. RPN really is cool, and prevents people from borrowing
your calculator.

I can't put my finger on why, but the samsung calculator is annoying.

Factually incorrect:

Casio fx-77 scientific calculator photo (1/x key visible):

https://upload.wikimedia.org/wikipedia/commons/4/4f/FX-77.JPG

HP-35 photo (1/x key visible):

https://upload.wikimedia.org/wikipedia/commons/3/34/HP-35_Red_Dot.jpg

HP 15C photo (1/x key visible):

https://upload.wikimedia.org/wikipedia/commons/6/65/Hp15c.jpg

At least 90% of calculator apps on Google Play do not use "1/x", instead
they use "X-1".

This nym-shifting troll, never before posted to this group under its
current ID, points to Wikishit (for some strange reason) and mostly
Hewlett-Packard calculators, after I said "normal calculators".
Everybody knows HP calculators have never been considered NORMAL.

And why are 'apps' relevant. Up until this post, you mentioned:

"normal (scientific) calculators"
"a typical scientific calculator"

Neither of which relate to calculator apps on google play.

Because they have lots of images that are publicly available.

Three HP calculators out of five total is hardly "mostly". But in any
case, there were photos of a TI and a photo of a Casio calculator
referenced, both of which have 1/x as the label for reciprocal.

> after I said "normal calculators".

Which to everyone sane means: "calculators" not "apps on google play".

> Everybody knows HP calculators have never been considered NORMAL.

HP calculators are just as normal as TI or Casio calculators. Do not
confuse less common or expensive with normal, they do not mean what you
think they mean.

I use Droid48 Same as an HP48 and I think it actually uses the HP48
software emulated in the Android. So the math is (or should be) as
good.

either way, it is VERY good.

I also carry an HP15C in my bag of tricks.
