- The continued fraction expansion of Riccati's differential equation is not implemented
- integrate((1 - x**4)**(-1/3), (x, 0, 1)) causes an error
- Unnecessary complications with Sum((4*k + 1)*factorial(k)/factorial(2*k + 1), (k, 0, n))
- 1/2 + Sum(cos(k*t), (k, 1, n)) cannot be calculated
- x - 1 is not recognized as a factor of x**n - 1
- Increasing the scope of summation

- On salvaging #104 (Integral equation stuff)
- Sum(binomial(n,m)*x**m, (m, 0, n)) is given an irrelevant convergence condition and there is a strange factorization when y's are present
