I believe 3\pi(x)3π(x) means 3\pix3πx, this notation doesn't make any other sense to me.
If so, the period must be 1/313.

We know that the period of tan(\theta)tan(θ) is \piπ, and we know that adding a constant and multiply by a constant outside doesn't change the period.
So it must be the same period of tan(3\pix)tan(3πx), which is trivially 1/313
