Thanks! Maybe I expressed myself misleading. Also the output in my yupyter notebook did not correspond to what is in the documentation. I have difficulty to understand the output of the three calls below which are taken from the doc-pages I cited. ----------------------------------------------------- from sympy import rf, symbols, factorial, ff, binomial from sympy.abc import x n, k = symbols('n k', integer=True) rf(x**3, 2) # ? x**3*(x**3 + 1) rf(x, k).rewrite(binomial) # ? RisingFactorial(x, k) rf(n, k).rewrite(factorial) # ? RisingFactorial(n, k) ----------------------------------------------------- Perhaps someone can enlighten me what to expect and to tell me if the output of SymPy 1.0 is correct?
