Find the absolute maximum and minimum values of the following function on the given interval. Then graph the function. Identify the points on the graph where the absolute extrema occur.

Question

cos (theta) , -pi ≤ theta ≤ pi/4

Answer 1

At theta = -pi, cos(theta) = -1 and this is an absolute minimum on the interval specifed.

At theta = 0, cos(theta) = 1 and this is the absolute maximum of the specified interval.
