Hi guys,
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??
