Hi guys,(adsbygoogle = window.adsbygoogle || []).push({});

Stuck on an integration by parts question....Not going to post the question as I want to work it out myself, but as I'm a bit of a novice on diff/integration I'm stuck on what we do at a certain step of the process....anyway..

I know integration by parts we end up using ∫udv = uv - ∫vdu

where obviously we assign u,v,du,dv as parts of our equation..

Now what I'm stuck on is what happens if we have say 1/2 ∫ udv = uv - ∫vdu

how does the 1/2 effect how it's processed?

does it end up as

1/2 ∫ udv = uv - 1/2∫vdu

or something like

1/2 ∫ udv = 1/2 uv - 1/2∫vdu

Anyone able to explain (reasonably simply) how it ends up and why??
