Question

At which value will the graph of y=csc(x) have a zero?

pi/2

pi/4

pi/3

none

Answer 1

is it none

Answer 2

well start with

csc(x) = 1/sin(x)

and the basics of fractions is that you can't have a zero denominator

so the curve never touches or cuts the x-axis

there are asymptotes every pi units from the origin
