As x approaches π from the right, the value of the function f(x) = cos(x) approaches

Core Concept

The cosine function approaches 0 as its input approaches π from the right. This is because the cosine function is continuous everywhere, and the limit of cos(x) as x approaches π is 0. Option B and C are incorrect since the cosine function does not approach 1 or -1 as its input approaches π. Option D is incorrect since the limit of f(x) as x approaches π does exist.
