Best ResponseYou've already chosen the best response.0that its undefined because its domain in standard form is all real #s except pi? I am not sure, I am guessing

Best ResponseYou've already chosen the best response.0Right, the domain of cot(x) is all reals except for integer multiples of pi. So not at 0, pi, 2pi, ...

Best ResponseYou've already chosen the best response.0So if this is cot(3x), then 3x cannot equal n*pi. Now solve for x

Best ResponseYou've already chosen the best response.0No. What @Tonks means is "solve of x in terms of n and pi", I believe. He's stating an easy statement in a very formal manner.

Best ResponseYou've already chosen the best response.0No, I mean in a statement like 3x = n*pi, isolate x on one side and everything else on the other by dividing by 3...

Best ResponseYou've already chosen the best response.0That compression will move the asymptotes, like an accordion, toward the origin.
