Grasshopper

algorithmic modeling for Rhino

Periodic sinus like S-Curves/sigmoid curves/easing curves, etc.

Hi,

i am a very newbe, and unfortunately quite bad in math, but for a project i need to draw a parametric curve like the ones mentioned in the title. Basicaly those are sinus wave like curves. I found a lot of examples about the basic formulas, like easing equations (from Robert Penner for example), or logistic function via wiki, etc..

If someone can tell me what is the key to do, it would be great, because i realy searched a lot but found nothing.
I drew some examples in Illustrator, it shows clear what i thinking about.

Thank you!

Not a mathematical solution, but could work sometimes.

This is a little bit more mathematical.
