.
The problems in this section are conceer with the method of integration by parts which is simply the following ff'(x>s(x) dr =f(x}s(x) — [mums Here we have written the functional as opposed to differential form found in the book [mm—[van so do = f'(x}dx and v = g(x). In this exercise we want to use Integration by parts to integrate [x sin(x)dx mm —dx and(0} Evaluate thelntegrai -xcos[x}+sin[x] +0
