To me, it is remarkable how often it pops up. The number has aesthetic value in its definition and associated properties: The definition of e is the limit as n approaches 0 of (1 + n)^1/n and one nice, unique property of the function e^x is that the derivative of the function e^x is the function e^x. In addition, e comes in handy in many real life problems, like problems dealing with investment and banking. More exciting, there is an e home page! Check this out: http://www.missouri.edu/~c639692/exp/ From this page you can go to lots of other pages that all relate to e. Being an enthusiast of the function e^x, you would especially enjoy the following link: http://pauillac.inria.fr/algo/bsolve/constant/e/e.html You can get to this second link from the first, but in case you want to go there directly, I include the second URL. These two links have lots of interesting stuff in them about e and the function e^x, so I hope you enjoy them! Good luck. -Doctor Sydney, The Math Forum Check out our web site! http://mathforum.org/dr.math/
