Determine the value of csc (pi/2).

Csc (pi/2) or the cosecant of (pi/2) can be obtained by using a calculator.

In terms of degrees, pi/2 is equivalent to 90 degrees. Cosecant is also the reciprocal of sine. Since sin 90 is equal to 1, obtaining the reciprocal of 1 should yield csc (pi/2). Since the reciprocal is simply equal to 1, then:

csc (pi/2) = 1
