Explain whether it is sometime, always or never possible to find the the maximum and minimum values of the functions. Give reason also.

Answer to Problem 60HP
There will be “sometime” to find the maximum and minimum values of the function.
Explanation of Solution
Given: It is given in the question that there is a amplitude and period of a cosine function.
Since, in a cosine function, the function could be moved to the right or left or up to down.
As long as the function is still based around the origin, it would be able to find a maximum and minimum just using the period and amplitude.
