Best ResponseYou've already chosen the best response.0This function appears to be undefined at x=.25 radians and selected multiples thereof. These values, I think, should be excluded from the domain. Given that the secant function is discontinuous, I doubt the domain would be the set of Reals.

Best ResponseYou've already chosen the best response.0D:{x(x≠1/4+n/2), n∈I x∈R} would be the correct answer i think. sorry for that haha.

Best ResponseYou've already chosen the best response.0hmm so {xx≠kpi/4,k is an odd integer) would be another format to say the same thing?

Best ResponseYou've already chosen the best response.0saying kpi/2, where k is an integer would be a better way of saying it

Best ResponseYou've already chosen the best response.0how does it change from kpi/4

Best ResponseYou've already chosen the best response.0saying kpi/4 and saying that k is an odd integer is kinda bizzare. saying kpi/2 and saying that k is an integer would be a better way.

Best ResponseYou've already chosen the best response.0just to be clear, you are sure it is kpi/4 and not k/4
