If you look at the five components of Euler's identity: pi, 1, 0, e, and i. You can see that only one component, pi, isn't the real pi that we think of. Instead, pi in this case simply represents 180 degrees. But degrees can be represented by any other symbol, therefore pi isn't really pi in this instance.

Or am I wrong.

Sure. And instead of choosing 'e' to represent the natural base, we could have chosen 'z'. Instead of choosing i^2 = -1, we could have chosen e^2 = -1.

What's your point?

Edit: z^pi*e + 1 = 0

My point is that pi=3.1419..., which is a ratio

But in the case of Euler's identity, pi=180 degrees.

The two uses of the symbol pi have very different functions.

Err... e^{ix}=cos(x)+isin(x)

Simple proof. Subsitute "pi" in the equation and OMG you get TEH identity!


I know that, Genius, that's why I'm asking the question of why the euler's identity would make people see pi(3.1419...) when they are actually seeing pi(degrees). At worst, it's a perversion. Hence, the identity is not as beautiful as many see it. It can be beaufitul, but only if you believe something that really isn't what it espouses to be.


We're seeing pi (3.1419...) radians. What's the problem here?

OP, I suggest you read this.

I know the identity is correct but...others may think that they can simply plug in scalar pi and out will come 0... Never mind, I think I'll leave this one alone.

what?

I'm saying disregard the question. Forget it. Forget I asked it.

Wait a second...you're saying it's a perversion because you assume people would plug in 3.1415... degrees hoping to get 0? :confused:

I should hope that someone who makes it to a class at that level of math would know what a radian is...

Anyway, I imagine you're now wondering what the protocol is in regard to the proper way to back out of a situation such as this. Let me give you a head start:
oh well who cares, i wont admit i am wrong, even though i may be(which i most likey am). But not at the part of pi isn't really pi in this instance. I WILL SAY THIS AGAIN, MOD PLEASE LOCK THIS ONE, AS I HAVE SEEMED TO START A CONTROVERSIAL TOPIC.

You're welcome :thumbsup:

e^i(pi) +1=0

where e^i(pi)= cos(pi) +isin(pi)=-1

But a^x>0>-1. If you've taken modern analysis (which I haven't) or number theory, perhaps you can enlighten me and the average joe on this equation by explaining exactly what i is.

I'm not saying the equation isn't beautiful (in it's simplicity), but there's a wholly complex dimension that undermines such beauty. Perhaps I'm being more philosophical than mathematical, but that's precisely my point.

I agree it's complex but it's not complex due to the fact that pi degrees != pi radians.

If you don't know what a radian is you should be banned for even starting a mathematics thread. And if you think that the number pi (3.14....) is unrelated to the pi in the unit circle on a complex plane then you clearly have no clue what a radian is.

It IS pi you mothafvckin' idiot. Goddamn I've never seen such an moronic thread in my life, and I've been around a while.

There was a NY Times poll of prominent scientists, mathematicians, etc asking what the most famous/important equation was. The winner was Euler's Identity, with Maxwell's Equations taken as a whole a close second. Other contenders were E=mc^2, F=ma and 2+2=4.

AHAHAHAHAAAAAaaaaa

I know what you meant, but that still made my night. :laugh:

I think Maxwells Equations rounded out the top three didn't they? Or was that a different survey?

lol you're too fast for me :) I just went to look it up and edited my post...couldn't find the article, but I found a blurb about it. You are right!

The pi in this case represents half the circumference of a unit circle.

All the numbers were at a party and having great fun, expect e which stood alone in a corner. So 5 came over and asked: "Hey! Why don't you join us over there?" To this e answered: "Well, I just can't integrate myself!"

HAAHAAAH HAH HAH ha... hm :(
