The infinite integral converges but is hard to evaluate because the integrand f(x) = x/(1 + x
6sin2
x) is a non-convergent and unbounded function, indeed f(kπ) = kπ→ ∞ (k→ ∞). We present an efficient method to evaluate the above integral in high accuracy and actually obtain an approximate value
in up to 73 significant digits on an octuple precision system in C++. |
