Given information
Here given a function .
We have to Show that is continuous on .
Step-by-step explanation
Step 1.
By theorem 7, the trigonometric function are continuous. Thus, on and on are continuous.
Thus, is continuous on .
To check continuity of at , we will evaluate left hand limit and right hand limit.
as the sine function is continuous at .
by continuity of cosine function at .
Thus,
Therefore, is continuous at , so is continuous on .
