-
Prove the following theorems of Archimedes:
1^2 + 2^2 + 3^2 + ... + n^2 = n(n+1)(2n+1)/6,
sin pi/(2n) + sin 2 pi/(2n)
+... + sin (2n-1) pi/(2n) = [cos pi/(4n)]/[sin pi/(4n)]
-
Devise observational
methods to (a) Compute the length of the year. (b) Compute
the dates for the astrological signs of the zodiac. (c) Order
according to size: earth, sun, moon.
