Webnonnegative so that the comparison test for convergence can be used. Comparison test for convergence: If 0 f gand R g(x)dxconverges, then R f(x)dxconverges. Remember the picture: To apply this test, you need a larger function whose integral converges. Comparison test for divergence: If 0 f gand R f(x)dxdiverges, then R g(x)dxdiverges. http://www-personal.umich.edu/~mconger/dhsp/lct.pdf

Integral test for convergence - Wikipedia

WebThe idea of this test is that if the limit of a ratio of sequences is 0, then the denominator grew much faster than the numerator. If the limit is infinity, the numerator grew much faster. If your limit is non-zero and finite, the sequences behave similarly so their series will behave similarly as well. Limit Comparison Test: Let ∑ n = 1 ∞ ...
