The period of y=4cos5x 2π/5
-
True
-
False
That's Correct!
It's Wrong!
The given equation is in the form y = A*cos(Bx + C), where A = 4, B = 5, and C = 2π/5. The period of a cosine function is given by 2π/B. Therefore, the period of y = 4cos5x is 2π/5. Since the given equation has an additional term of 2π/5, the period is still 2π/5. Hence, the answer is True.
