Given that the image of the function f (x) = 2Sin (Wx + π) is symmetric with respect to the line x = π / 3 and f (π / 12) = 0, what is the minimum value of W

Given that the image of the function f (x) = 2Sin (Wx + π) is symmetric with respect to the line x = π / 3 and f (π / 12) = 0, what is the minimum value of W

In other words, when x = π / 3, there are only 3 / 4 cycles, while when π / 12, it is equal to 0, which is exactly 1 / 2 cycle. Therefore, the formula can be reduced to - 2sinwx
3 / 4t-1 / 2T = π / 3 - π / 12 = π / 4, that is, t / 4 = π / 4, so t = π, w = 2 π / T = 2
