Question

At which value will the graph of y=csc x have a zero?
A, pi/2
B. pi/4
C. pi/3
D. none of the above are correct.

Answer 1

y = csc(x)

y = 1/sin(x)

0 = 1/sin(x)

0*sin(x) = 1

0 = 1

Since this equation is never true, there are no zeros for the function

Answer 2

D

Answer 3

Agreed thanks a lot i was just a bit unsure
