I try to simplify this Piecewise expression using refine without success. I use sympy version 1.8. import sympy as sp x,y = sp.symbols('x,y', real=True, positive=True) expr = sp.Piecewise((1, x>=...

The function get_cubic needs 4 points and i need to find b and c by calculation (a and d is given). Here is my code and i need help specifically with get_bezier_coef def get_bezier_coef(points): #...

I'm trying to make a piecewise linear fit consisting of 3 pieces whereof the first and last pieces are constant. As you can see in this figure don't get the expected fit, since the fit doesn't captur...

I would like to define the piecewise function below using the sympy module and then calculate a Fourier series for it. Unfortunately I have no idea how exactly this works and have not found anything h...
