How to show an integral diverges

WebThen, ∫b af(x)dx = lim t → a + ∫b tf(x)dx. In each case, if the limit exists, then the improper integral is said to converge. If the limit does not exist, then the improper integral is said to diverge. provided both ∫c af(x)dx and ∫b cf(x)dx converge. If either of these integrals diverges, then ∫b af(x)dx diverges. WebDetermine whether the series diverges using the divergence test for series. ∑ x=1∞ [x + 1] / [x] Solution Apply the divergence test and replace the sigma notation with the limit of the function as x approaches ∞. ∑ x=1∞ [x + 1] / [x] = lim x→∞ [x + 1] / [x] Use L’Hopital’s rule and differentiate both the numerator and the denominator.

Integral Test - Definition, Conditions, and Examples

WebWe consider three integrals which include a parameter: For each, we determine the values of the parameter (p or a) for which the integral converges and diverges. These derivations are performed in the following examples.
