What is the square root of pi?

Huh?

All your pi are belong to us.

Circumferance devided by diameter = Pi.

The only imaginary numbers I deal with have to do with future earnings and sex. : )

If it is an imaginary number, then it can be any number. I suppose I should have said there is no square root of any REAL Minus number.

In the prinicples of logic the words NO and ALL makes it distributed. Therefore it should have been understood that we were talking about Real Numbers. : )

Check out Peter Beckman's surprisingly entertaining book, History of Pi.

Pi is a transcedental number, which means that it cannot be expressed as the solution of an algebraic equation with a finite number of terms. (No, it does not mean it lives in a shack in woods in Massachusetts.) All transcendental numbers are irrational, which means that they cannot be expressed as the ratio of two whole numbers. (No, it does not mean they are life-long Democrats). As a consequence of this property, an irrational number can never expressed as a finite decimal fraction, else it would be equal to the decimal fraction without the "." over "1" followed by as many zeros as there are digits!

It should be easy to prove to yourself that if you could write a finite decimal expression for the square root of Pi you could square it, and have a finite decimal expression for Pi! And you would be famous, win a MacArthur foundation Genius grant, the Fields Medal and be the envy of all your friends.

Not all irrational numbers are transcendental, for instance x*x -2 = 0 has the roots +/-sqrt(2), so the sqrt(2) is irrational, but not transcendental.

Another familiar and useful transcendental number is "e", the base of natural logarithms. It the limit, as n approachs infinity of (1+1/n)^n or 1/0! + 1/1! + 1/2! ... to infinity. Or about 2.718281828...

(22/7) or, 3 1/7 or, (22/7)^1/2 or, (3 1/7)^1/2

First you have to start with the value of pi which was written into law in Indiana:

Quite a boondoggle ---

Read Beckman's book, #265. The bill never got out of committee, fortunately for the progress of Science along the Banks of the Wabash.

Try gamma(0.5) if you have matlab.

Heck, close enought for gov't work would be ...oh...like... 12?

Also, there are hundreds of mathematical types on FR who look at every technicality.... LOL!

While we are at it, what is the square root of negative 1?

"i"

what's wrong with you? all pies are round and most are not made from roots!

Sweet potato pie, anyone?

What would a DOG scan reveal?

Why is six afraid of seven?

Because seven eight nine.

But then six got an attack dog named five. What for?

Four five six seven.

Interestingly enough, the legislature of South Carolina (as I recall the state) once decided that pi was confusing the school kids and was too difficult to remember and interfered with tidy calculations. They therefore passed a law that the value of pi in South Carolina would henceforth be 3.00000.

I heard that it was Indiana. Which one (or perhaps both) did it?
