Incorrect definite integrals due to incorrect handling of branch-cuts

1

The correct value of this integral is π, However Rubi gives 2π when the integrand has exponentials and π (correctly) when it is trigonometric. The antiderivative with exponentials has ExpIntegralEi[z]...

n-th prime is too slow. Consider using primecount as a backend

21

The n-th prime function of julia is actually really slow. For example in julia prime(10^7) runs in 14 seconds in my machine. There is a well known C++ library with...
