(...nothing up this sleeve, nothing up that sleeve...)

But, for the record, the positive square root of the square of a quantity is equal to the absolute value of the quantity; it is not equal to the quantity with its original sign. That is,

√[ x² ] = |x| .

Hence, since

√[ (-1)² ] = |-1| = 1

and

√[ (1)² ] = |1| = 1 ,

there's no contradiction.

Shame on you, g_w, for giving KP a headache!

Sorry to disagree with you for once, snarks, but the last words in my post were (and I quote from memory):

Tee hee.

It was a jest.

(I saw it on in a T-shirt catalog once, next to the "Reunite Gondwanaland" and "If you're not part of the solution, you're part of the precipitate".)

Cheers!

...and BTW, great job on the radical signs in HTML in your post.
