How do I find & calculation the coeffiecients if a Chevychev Polynomial for a sine wave? It seems as though the coeffiecients vary greatly depending on the precision you want the computer to calculate them (4-byte, 8-byte, etc.) Why? Is there such a polynomial for exp, ln, ATN, etc. Any easy-to-understand reference materials?

I know next to nothing about Chevychev Polynomials other then their range is from zero to one.

I understand that the probability of tossing a coin and it landing or either heads or tails is 50% and that flipping it again is an "independent event" and does not change the probability at all. That is, the chances of the coin landing on heads or tails is still 50% regardless of whether it landed on heads or tails the first time.

However, what about something like gasoline prices? Today, gasoline prices can either be up or down (50%). Similarly, tomorrow gasoline prices can either be up or down (50%). But what if gasoline prices were down today and a study of past gasoline price patterns ("empirical probability" from experimenting) demonstrates that if they are down today, they also have been down the following day (60%) of the time--a ten (10%) difference? Is whether gasoline prices were up or down today an "independent event" from whether they will be up or down tomorrow, or a "dependent event"? I'm looking for some definitional clarity here.

If you are a mathematician or know one, please answer (I can make stupid guesses for myself, so if you really don't know and just want to make points by answering please go to another question not mine). Thanks

I have the answer to this, too - but I may be doing it wrong.

If 6 men can do a piece of work in 14 days, how many men are needed to do the work in 21 days?

The easy answer is 9 (it takes 1 man to do a job in 7 days, making 9 men in 21 days.) But the answer here as "correct" is 4 men in 21 days - which could also make sense, but I don't know how to get to that answer?

Does anyone have the solution - something that actually makes logical mathematical sense - and with the working out please. Thank you! :)
