Let p be a symmetry center of image C with F (x) = SiNx. If the minimum distance between P and the symmetry axis of image C is Wu / 4, what is the minimum positive period of F (x)

Let p be a symmetry center of image C with F (x) = SiNx. If the minimum distance between P and the symmetry axis of image C is Wu / 4, what is the minimum positive period of F (x)

The nearest axis of symmetry P is π / 4
Then the point P is symmetric about the axis of symmetry is also the center of symmetry
So the distance between the two adjacent centers of symmetry is π / 2
That is, the half period is π / 2
So the minimum positive period is π
