How do you create a damped cosine wave?

[anonymous_user_c40fb0ba]

I am creating a circular cosine wave, and would like to damp the wave the further it is from the point of origin. Does anyone know how to do this? I’ve tried multiple things over the past two days and still am not sure. See the attached picture for my cosine wave setup.

Thanks a bunch,

You can use the ActorPosition to gradually decrease the wave amplitude.

This is basically the concept, except I have a div by zero problem at the moment:

… and because the remap node doesn’t seem to work right:
