What is e? A Ratio?
Date: 7/25/96 at 21:2:51 From: Anonymous Subject: What is e? A ratio? I am a high school math teacher. Yesterday at a conference an old buddy of mine asked me where e came from. I said huh? He said well, pi is of course the ratio of the circumference of a circle to its diameter. There must be some similar explanation for e. Is there?

Rather, it's a limit. n e = Limit (1 + 1/n) n -> infinity 'e' can also be expressed as a sum: infinity ----- \ 1 e = ) --- / i! ----- i = 0 -Doctor Paul, The Math Forum Check out our web site! http://mathforum.org/dr.math/
