a.
To identify: The trigonometric function that are even and odd if a function
The cosine function is even and the sine and tangent functions are odd.
Given information:
An even function is
Explanation:
The given functions are: An even function
The trigonometric cosine function is even and the sine and tangent functions are odd.
On the other hand,
Therefore, the cosine function is even and the sine and tangent functions are odd.
b.
To state: If all the functions either even or odd also give a counter example if possible.
No, all the functions are not either odd or even.
Given information:
An even function is
Explanation:
No, all functions are not even or add.
The reason being
Whereas
Therefore, all the functions cannot be defined either odd or even.
