Question
What is the period of y = 3cos (8x + π/2) + 5?Question 15Select one:a.2πb.πc.π/2d.π/3e.π/4
Solution
The period of a cosine function is given by the formula 2π/B, where B is the coefficient of x in the argument of the cosine function. In this case, B = 8. Therefore, the period of y = 3cos(8x + π/2) + 5 is 2π/8 = π/4. So, the correct answer is e. π/4.
