Step-by-step explanation
Step 1.
It is clear that and are continuous for in . Since, polynomial and trigonometric functions are continuous in their domains.
is continuous for on . Since, the composition of continuous functions is a continuous function.
is continuous on . Since, the product of continuous functions is a continuous function.
As
Therefore, by squeeze theorem,
Since,
