Sine around a curve

Hi,
I want to wrap a sine wave along a curve. I have tried a couple of things but it’s turned out a non-symmetrical wavy curve.
Thanks in advance.

Thank you. However, it seems it is not working for closed curves.

There is another topic with different solutions but I don’t find its link

You could do half and mirror it.

here a solution . It is a simple Math problem. If you want something symetric you MUST have a domain inside the Sinus that is a multiple of 2 * PI. Sin(x) = sin(x+ 2*pi).
