### I'm not sure why but I dreamed about this equation

7√ π ^3

Not sure how to type all the math stuff but basically..

7th root of pi to the 3rd.

I have no idea why, but this equation has been stuck in my head for months.

hi Don

Is this your dream?

Doesn't ring any bells for me but maybe you have stumbled upon a new and significant constant.  Let's call it dford's constant.

The 'math stuff' is called Latex.  Have a look at

Yep that was my dream. If it turns out to mean something I'd be happy.

Hi dford;

Does that number come out of a problem you were working on?

To 14 decimal places the ancient Egyptians would represent that as:

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.

Hello everyone
why would anyone use such constant upto 14 decimal places........??
And what is that series called....??

### Re: I'm not sure why but I dreamed about this equation

And just as dford i'm stuck with
e^(i*pi)+1=0.......
Does anyone know what is that supposed to mean........???

Hi Maiya

That is just an equality that many people find intriguing because it connects 5 major constants in math: e,pi,i,1 and 0.

The limit operator is just an excuse for doing something you know you can't.

That is called an Egyptian fraction.

### Re: I'm not sure why but I dreamed about this equation

Hello anonimnstefy....
how did someone end up with such an equality??
I mean i've tried it many times but i never got that equation right........
I could never compute e^i......
And can anyone put some sense into that equation....

hi Maiya

It comes from complex number theory.

A number of the form

means it has an 'argument' of theta measured anticlockwise from the positive x axis.

### Re: I'm not sure why but I dreamed about this equation

oh ya right.......exactly....
e^(i*pi)=cos(pi)+i sin(pi)....
why didn't i think of this before....
thank you bob....
