Perfect! As I'm making my way through the joy of learning to use slide rules this is exactly the video help I've been looking for--many thanks for posting! Very helpful, Dave.
Regarding 1:21, e^(-x) does not equal e^(1/x). Instead e^(-x) = 1/e^x. This is because a number raised to its negative exponent is the reciprocal of that number.
1:21 e^(-x) doesn’t equal e^(1/x), it equals 1/e^x. Else the negative of a number would equal its inverse, which would mean that any number x would equal 1/x^(2n) and on the same time -1/x^(2n+1). Which actually would mean that all numbers equal 0 (when n goes toward infinity). That doesn’t really make sense!

Thanks very much!
Very interesting and very well explained thank you.

Thanks for clarifying! I’m really not a great mathematician, and have already forgotten many of the things I demonstrated in this video.

Thanks for clarifying. I must admit that I’m really not great at maths - I just enjoy playing with these things!
