I am working on something not associated with homework and I need some help figuring out how to calculate the points of a graph. I'd like to have an exponential curve with 72 datapoints where every 8 points a new sinwave starts. The math is way over my head but I am sure my fellow math nerds know how to solve it quickly. The image below provides you a better idea of what I am thinking of. Don't take the image literally for anything. It is just an example.
