Integration by parts is a successful method when we can choose an appropriate u and dv so that on the right hand side we end up with an integral that is easier to work with than the original. Answer and Explanation: We don't have much of an option on o...
we will use integration by parts and a substitution method. Let's go through the solution step by step. Step 1: SubstitutionLet t=lnx. Then, we differentiate both sides: dt=1xdx⇒dx=xdt=etdt. Next, we need to change the limits of integration. When x=1, t=ln(1)=0. When x=e...

Academic proofs usually tend to be as rigorous as possible, and are carefully verified by other experts in the field, to be objectively certain of its correctness. Clearly that is not a level of rigor you need while solving a codeforces problem. You only need to prove itto yourself. ...
Any positive linear functional on the space of compactly supported continuous functions on a locally compact Hausdorff space can be viewed as integration against a measure. Kapovich-Millson Universality Theorem. Any compact smooth manifold is diffeomorphic to a component of the configuration space of ...
Jacob Riis was among the first photojournalists.He took pictures of parts of New York City where the poor lived.Riis believed that poverty(贫穷) caused crime,and he used photos to help him prove his point.A few years later,the photos of small children working in factories b...
