There seems to be a general belief that all knowledge has been written in books. I found relations I never saw in texts, so it must not be true. I rewrote EE expressions so they were easy to remember and use with the HP RPN system. I would like to hear from you whether you were able to use any of the information. You may write directly using the above name @cox.net Thanks, Sam
