- Thanks for all of your relies. I found them all interesting and
- helpful. I guess it was kind of worded like a 'stupid' or
- 'obvious' question but I meant it in all sincerity.
-
- So thanks for not flaming me (yet)!
-
- Actually there's a related point I haven't been able to grasp
- intuitively. How about that -other- number: e
-
- Okay, I won't ask why it's between 2 and 3, irrational, etc...
-
- It's just that Euler identity... I can't seem to wave my hands
- around in the right way to imagine what it means to multiply
- e (or any number) by itself an imaginary number of times!
-
- Okay, I know we can justify raising a base to an irrational
- exponent using logarithms, but it doesn't seem to me to justify
- the same thing for imaginary exponents.
-
- Of course, I have seen the Taylor series proof of Euler's
- identity but I can't seem to pull any intuitive feeling out
- of it. It seems to me as well that having proved Euler's
- identity, you then have a strong link between e and Pi.
- Is this not so? I was wondering whether anyone knew how strong
- this link might be and whether we can express e and Pi in terms
- of each other in any useful way?
-
- In engineering we seem to get enough math to be able to use it
- to solve problems but it's not deep enough to get comfortable
- with it. By the way I just found out today I passed the
- Partial Differential Equations exam after writing it for the
- third time.
-
- Congrats, flames, comments?
