S.O.S., emergency! ALGEBRA AND THEORY OF NUMBERS
dear members of community, i need your help a lot!
the problem is - i can't find any info on topic
"theory of divisibility in the ring of polynomials with TWO variables and their usage"
i've looked through all catalogues of our uni library but in vain, there is only one Russian book which is not enough for my research.
if you can advise relevant links on free e-materials or send me the scanned books on topic (firstname.lastname@example.org), i'll be very-very grateful!
THANKS IN ADVANCE!
So, I've had this random joke in my head since I took first place in the city calculus competition. Just a quick insult I've had ready made, in equation format.
lim f(x) = undefined
f(x) = 1/x
^__^ Yet another tally on the "you might be a geek if" list...
Golden Mean, Golden Ratio
This number can be defined as
1/x = x+1
or calculated this way
(√5 - 1)/2
The ancient Greeks firured this number, used as a proportion, was the most beautiful and many ancient Greek buildings show that proportion in their shape
I like to calculate it by entering 4870847 into the calculator and pressing the square root sign 5 times (gives you 1.61803398874989 which is the inverse of the Golden mean or 1 plus the golden mean to 14 decimals of accuracy) or 2207 and press the square root 4 times (1.618034)
interesting number index
0.61803398874989484820458683436564 (golden mean)
1.61803398874989484820458683436564 (golden mean)
