Match the following description to the correct value The lea

Match the following description to the correct value. The least positive value k for which x - k is a vertical asymptote for y = csc x Choose the correct answer below. pi 3pi/2 -pi -1 1 pi/2

Solution

The function y=cscx has vertical asymptote at those points where sinx=0 that is at n*pi

So csc x has vertical asymptote at x=0,180,360,540 etc

Hence the correct option is A
