What are the range and domain of y = tan x ?

Range = -pi/2 < x < pi/2
Domain = - infinity < y < + infinity or

Range = - infinity < y < + infinity
Domain = -pi/2 < x < pi/2 or

Range = - infinity < y < + infinity
Domain = -1 < y < 1 or

Range = undefined
Domain = - infinity < y < + infinity

I don't think so. Not that I claim to have seen any UFO's or been abducted. The line from the movie "Contact" says it all for me. "If we are alone in the universe - it seems an awful waste of space" I'm not sure if that is exact but you get my meaning. Any other thoughts?

Is there a good construction for the 21-sided regular polygon using only a ruler and a compass? I no that this is not possible, but I mean a good aproximation construction. Is there any?

I think I'd be able to solve this problem if I just new the equation... is it a combustion? What are the reactants if the product is CH3OH(l) and are there any other products? Thanks.
