What are or where can I find the mathematical formulas for "the Greeks" regarding option's value calculation?

Question

I would like to purchase options with a level head and realistic expectations.

Answer 1

http://en.wikipedia.org/wiki/Greeks_(finance)

has them, but it is far easier to use an options calculator, such as the one at

to calculate them.

Answer 2

Unless we can start redeeming every thousand points mark with say vouchers for beer (or wine if that be your preference) I fail to see any worthwhile reason to the whole idea of accruing points? I'm serious. It's like achievements earned when completing games on the Xbox 360 in reality about as much use as a chocolate fire surround. Hence probably though the reason why when someone asks an inane question like the date of Mozart's birthday why we then get like twenty answers all essentially saying the same thing when one answer would usually suffice. To those individuals, what's wrong with simply leaving a thumbs up? Oh yes that's right you won't receive a worthless couple of imaginative points. They are not a barometer for measuring anything of any substance or certainly of any worth. Yes best answers are a bit different but they could be awarded devoid of any points tally. As regards best answers that aren't picked and the huge amount that end up in a public vote. This certainly needs fixing. I don't know if anyone is aware but you can actually vote for your own answer. Now I find that to be downright dishonest because how can you be sure that the individual is being upright and truly evaluating all the answers given and fairly picking the best one totally free of bias towards their own response already submitted. Well in truth we can't so the whole process of best answers is infected and as such can never give a true assessment of any individual.
