Question

What are the x-coordinates for the maximum points in the function f(x) = 4 cos(2x − π) from x = 0 to x = 2π?

Answer 1

In the interval ([0, 2pi]), (cos(theta)) is maximum when (theta = 0, 2pi). Therefore, (cos(2x - pi)) is maximum when (2x - pi = 0, 2pi) or

(x = pi/2, x= 3pi/2)

Answer 2

Answer:

x=pi over 2; x=3 pi over 2
