Partial credit questions should take about 8 minutes to complete. At the lower bound, as x goes to 0 the function goes to ∞, and the upper bound is itself ∞, though the function goes to 0.Thus this is a doubly improper integral. Here we use the substitution u= lnx, so du= 1 xdx, and we get Z e 1 1 x(lnx)2 dx= Z 1 0 1 u2 du. Q1.3/2: Question 2 in section 1.3. Ans. Accepted File Types PDF Document Pdf c.
