You can use the same way as I showed for other similiar question.math.stackexchange.com/questions/166981/…

comment Analysis of the function $\prod_{n=-\infty}^{ \infty }(1-e^{-a{(x+n)^2} })$
@sonystarmap Wonderful result. Exactly As I expected in theory. I wonder if the function can be expressed as f(x)=A(a)sin2πx or not. I mean if G(x,a) does not to depend on x . I try to prove or disprove it now. Maybe you can help me via Matlab codes draw G(x,a).Is it possible depends on only a ? Thanks a lot
