complete the sentence below. on the interval π,2π, the function values of the cosine function increase from to
Answer
Explanation:
Step1: Recall cosine - function values
We know that (y = \cos x). When (x=\pi), (\cos(\pi)=- 1). When (x = 2\pi), (\cos(2\pi)=1).
Step2: Analyze the interval
On the interval ([\pi,2\pi]), the cosine - function is increasing.
Answer:
-1; 1
