Hint: In this question, we need to find the value of cosec 0o . We can find the value of cosec 0o by using trigonometric identities and ratios. The cosecant is nothing but a ratio of the hypotenuse of a right angle to the opposite side of the right angle. The basic trigonometric functions are sine, cosine and tangent. The values sin0o are used to find the value. With the help of the Trigonometric functions , we can find the value of cosec 0o .
Formula used :
cosec θ=1sinθ
Trigonometry table :
Angle 0o30o45o60o90o
sine 01212321


Complete step by step solution:
We can find the value of cosec 0o by using the cosine function.
We know that
cosec θ=1sinθ
Here θ=0o
Thus we get,
cosec 0o=1sin0o
From the trigonometric table, the value of sin0o is 0
By substituting the known values,
We get ,
cosec 0o=10
By dividing,
We get ,
cosec 0o=
Thus we get the value of cosec 0o is equal to which is infinite or not defined.
Final answer :
Since the value of cosec0o is infinite, therefore the value of cosec0o is not defined .

Note: The concept used in this problem is trigonometric identities and ratios. Trigonometric identities are nothing but they involve trigonometric functions including variables and constants. The common technique used in this problem is the use of trigonometric functions. Geometrically, cosec 0o lies in the first quadrant. We need to note that 01 is 0 and 10 is .
