It is known that the period of F (x) = asinwx + bcoswx, (W > 0) defined on R is Π, and f (x)

X &;, X &; ∈ (0, π) indicates that X &; and X &; are in the same period,
F (X &;) = f (X &;) = - 2 shows that X &; and X &; are symmetric about a certain axis of symmetry, x = a, a ∈ (0, π)
From F (x) ≤ f (π / 12), we know that the axis of symmetry in a period is x = π / 12,
The distance between two adjacent symmetry axes is t / 2 = π / 2
So a = π / 12 + π / 2 = 7 π / 12, i.e. X &; + X &; = 2A = 7 π / 6
