Integration By Parts

Integration By Parts

1. Performing Integration By Parts $\int f(x)g'(x)\,dx=f(x)g(x)-\int f'(x)g(x)\,dx$

1. Performing Integration By Parts $\int u\,dv=uv-\int v\,du$

Explaining

When you are looking at this equation

$\int u\,dv=uv-\int v\,du$

you may have been confused by u,du,v,dv

you can just under stand it as

1. u = f(x)
2. du = f'(x)
3. v = g(x)
4. dv = g'(x)
