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.

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

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.  smile

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

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

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 agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

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

And just as dford i'm stuck with

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.

That is called an Egyptian fraction.

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.

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