In fact fx -1xln2x 0 4 fn 1lnn So based on the integral test the convergence of the integral. In this section we will learn about another test called the Integral test. Calculus Problem Use Integral Definition To Calculate Calculus Definitions Education In the previous section we determined the convergence or divergence of several series by explicitly calculating. . If the given series meets these three criteria then we can use the integral test for convergence to integrate the series and say whether the series is converging or diverging. We have already done p 1 so assume that p 1. If 0 p 1 then 1 p 0 and lim D D1 p so the integral diverges. 211 N 1fxdx n N 1un. 1 1 xp dx lim D x1 p 1 pD 1 lim D D1 p 1 p 1 1 p. Then the series P 1 n1 a n is convergent if and only if R 1 1 fxdx converges Example Use the integral test to determine if. 1 1 xp dx lim D x1 p 1 pD 1 lim D D1 p 1 p 1 1 p. The Integral Test enabl
