6.3 Integration By PartsBadlands, South DakotaGreg Kelly, Hanford High School, Richland, WashingtonPhoto by Vickie Kelly, 1993
6.3 Integration By PartsStart with the product rule:(29ddvduuvuvdxdxdx=+(29d uvu dvv du=+(29d uvv duu dv-=(29u dvd uvv du=-(29(29u dvd uvv du=-(29(29u dvd uvv du=-u dvuvv du=-This is the Integration by Parts formula.
u dvuvv du=-The Integration by Parts formula is a “product rule” for integration.udifferentiates to zero (usually).dvis easy to integrate.Choose uin this order: LIPETLogs, Inverse trig, Polynomial, Exponential, Trig
Example 1:cosxx dxpolynomialfactorux=dudx=cosdvx dx=sinvx=u dvuvv du=-LIPETsincosxxxC++u vv du-sinsinxxx dx-
Example:lnx dxlogarithmicfactorlnux=1dudxx=dvdx=vx=u dvuvv du=-LIPETlnxxxC-+1lnx xxdxx-u vv du-
This is still a product, so we need to use integration by parts again.
