Inverse sinc function?

Hello
Is there a code to find the inverse sinc function?

sinc(x) = sin(x)/x

Doesn’t seem like it would be well defined. For a given y, there could be many x’s. You’d have to specify a neighborhood of x.

Hey!
I think you can have access to Sinc function by loading Numpy library.
https://numpy.org/doc/stable/reference/generated/numpy.sinc.html

I use a law in this page, it give an approximate result by solving the equation and find x

This is the best solution i found right now

This is another way with better precision (≈100%)
