Hint:

### Trigonometry is one of the branches of mathematics. There are six trigonometric functions and the limit of each of these functions leading to the point. However, we can calculate the limits of these functions according to the continuity of the function, considering the domain and range of trigonometric functions.

In this question, we have to find value of .

## The correct answer is: 0

= = 0
