Answer 1

well you can immediatly rule out cos(x) since it has no asymptotes. tan(x) has vertical asymptotes, but at every integer multiple of pi/2, so that can't work either. csc(x) = 1/sin(x) and sin(x) = 0 at x = 0, x = pi, x = 2*pi, so this seems to work, now for cot(x) = 1/tan(x), tan(x) = 0 at x = 0, x = pi, x = 2pi etc... so the only two answers are csx(x) and cot(x) so c) would be your answer

Answer 2

so A.

Answer 3

thanks :)

Answer 4

oh yes, sorry c) isn't it, it's a) :)
