start with a function that can be expressed as the product of two functions, u and v.
take the derivative of that function
Integrate that shit
∫ u’v = ∫(uv)’ - ∫uv’
and of course the ∫(uv)’ is just uv.
∫ u’v = uv - ∫uv’
I appreciate this post. I appreciate integration by parts.
integration by parts makes me feel so alive
