WebFeb 29, 2016 · I was asked to use Romberg integration to evaluate the integral$$\int_0^1x^{-x}dx=\sum_{n=1}^\infty n^{-n}$$ and compare the result with the result I get from the sum. And I also need to estimate how many function evaluation Romberg integration will require to achieve 12 digit accuracy.
