Final answer:

The exact value of csc π/2 is 1, since it's the reciprocal of sin π/2, which equals 1.

Step-by-step explanation:

The question asks for the exact value of the trigonometric function cosecant (csc) at the given real number, which is π/2. The cosecant function is defined as the reciprocal of the sine function. At π/2, the sine function, sin(π/2), is equal to 1. Therefore, the cosecant of π/2, which is the reciprocal of the sine, is also 1.

csc(π/2) = 1/sin(π/2) = 1/1 = 1.
