:I personally prefer (1/2)x^2 - C^2 because we can use the difference of squares factorization.

::Sure, but if you square the (variable) constant, then any result like (1/2)x^2+2 is impossible. Unless you really like complex numbers, of course - but most integration is done for functions which have "real" x. So the variant "(1/2)x^2-C" is "more correct" for the majority of people ;-) {{unsigned ip|91.89.211.18}} | ::Sure, but if you square the (variable) constant, then any result like (1/2)x^2+2 is impossible.

:as an altruistic individual, for everyone learning integration by parts, please look up both LIATE and tabular integration. You'll thank me later.
