Hint: In this question, we need to find the value of . We can find the value of 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 are used to find the value. With the help of the Trigonometric functions , we can find the value of .
Formula used :
Trigonometry table :
Complete step by step solution:
We can find the value of by using the cosine function.
We know that
Here
Thus we get,
From the trigonometric table, the value of is
By substituting the known values,
We get ,
By dividing,
We get ,
Thus we get the value of is equal to which is infinite or not defined.
Final answer :
Since the value of is infinite, therefore the value of 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, lies in the first quadrant. We need to note that is and is .
