单词	integral test
释义	integral test Let f(x) be a non-negative, continuous, decreasing function defined for x ≥ N, where N is an integer. Then, the series converges if and only if the integral converges. For example, setting N = 1 and f(x) = 1/x shows that the harmonic series diverges as tends to infinity as X tends to infinity.
