Multiple sin lines with damped amplitude

Hi,

I want to create a number of sin lines, 50 to be exact. Every second is rotated by 90 degree and the distance between every curve is 1cm. I was already able to implement all of those things but now i also want to damp the amplitude of every sin/cos curve the higher they go. So that the 50th curve, which is 50cm in the air is nearly a circle and not a sin function. I hope it is understandable what i am trying to implement.

Thank you for your help
