Math For 12 Year Olds

Quote from deadbroke:

for 12 -100 yr olds .....

Try this one - if nobody gets it, answer will be posted 1 yr from today. No hints will be given.


Starting from first principles and without the use of logarithmic tables, slide rules, computers, calculators etc., prove that

cot 7.5 degrees = sqrt 2 + sqrt 3 + sqrt 4 + sqrt 6

i.e. cotangent 7.5 degrees = square root of 2 etc.

Whoever reaches 100 first is the winner

A "numbers" game that will get you free beers (or cash in bets or pussy, the latter finding this sort of stuff quite xciting) in any bar in any country wherein the populace has a sense of humor. Currently for me anyway, the best country for this sort of stuff is ENGLAND, #2 being Scotland. Have yet to lose ... beats trading hands down.

I gave out the answer about 4 years ago, so it might have leaked worldwide. :D :D :D

It goes like this ....

any 2 fellas, A and B play it. Either one can start. Must start with a # between 1-10.

Objective = goal = slamdunk = whoever gets to 100 first, wins.

only one rule all responses after the opening # must be < or = stated # and 10 more.
 
Example:

A: 6
B: 15 (B can choose a # between 6 & 16, including 16, so he says 15. Dig?)

continue ...

A: 19 (A can say a # between 15 & 25, so he says 19)
B: 27 (B can say a # between 19 & 29, so he says27)

and so on ....

With said restriction of "no greater than 10 more" whoever can get to 100 first, is the winner.

Dig?
