I have a function I want to model. It is periodic, but the period keeps decreasing. Basically, it'll be a periodic function "squished" for larger values of x.
The typical Fourier series is...
y = SUM{aSin(nx)} + SUM{bCos(nx)}
I think I will attempt
y = SUM{aSin(nx^2)} + SUM{bCos(nx^2)}
replacing x -->x^2 should give me the "smushing" that I want.
The application is bladder level as a function of beers consumed. The basic function is an increasing (quadratic, exponential) function followed by a linear, steeply sloped drop to zero.
