I have a slide rule, I'd like to learn how to use it fully.
I have about 20 slide rules. Been collecting them since High School.
Which one do you have? Let me know what the scale names are (letters on the left) and I'll see if I have a manual for it (or something similar). I happen to collect the manuals too!
Here's mine.
I don't have any trouble seeing the tiny lines now.:wink:

Quick notes:
C & D are used to multiply & divide.
K for doing cubes and cube roots
A & B for doing squares and square roots
S for sin & asin
T for tan & atan
L for log (base 10)
C1 is the C scale backwards. Usually for reciprocals.
You need to be able to track the power of 10 and add on your own.
My favorite slide rule I have is a Sun Hemi 257 designed for Chemical engineering. It has molecular weights marked on it!
I didn't know they make slide rules out of logs.

Anyone remember the old HP calculators with reverse Polish notation? (I'm not making that up and it ISN'T an ethnic joke!)
