Answer:

csc π.

Step-by-step explanation:

csc π  because  csc = hypotenuse / opposite side  and the opposite side = 0. Anything divided by zero is undefined.

Another way to the same conclusion is:  we know that sin π = 0 and csc π = 1 / sin π = 1 / 0  which is indeterminate.

Answer:

cosec[tex]\pi[/tex]

Step-by-step explanation:

Only two function cosec[tex]\pi[/tex] and cot[tex]\pi[/tex] of the five trigonometric function are undefined .

From the given option cosec[tex]\pi[/tex] is undefined as we know that

sin[tex]\pi[/tex] =0 and cosec is inverse of sin. So,

[tex]cosec \pi =\frac{1}{sin\pi }\\cosec \pi =\frac{1}{0}  (sin \pi =0)\\ cosec \pi=[/tex] which is undefined.
