I do not think there is an answer. The question is worded all wrong.

Who knows what percentage of the given candy was eaten?

It is THE answer of a 6th grader's math question recently. You guys should return to elementary school again and make sure the teachers in your school district could do it.

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.

Several trigonometry functions were sitting in a bar drinking when a robber suddenly pops out .

He bellowed out ‘Give me your money or prepare to be differentiated!'

All of the trigonometry functions were terrified save one. That function said ‘Go ahead, I am the exponent of x."
