i forgot about integration by parts 
@Lucy fuuuuck that shit
@wallhackio @Lucy thanks for hating my post from 3 weeks and 1 day ago
@wallhackio @Lucy I don’t actually hate integration by parts I think my brain converted integration by parts to Taylor polynomials which have nothing to do with anything
@Lucy @wallhackio I just haven’t taken calculus since high school and only used it briefly when I took quantum mechanics in college
@wallhackio @Lucy I didn’t even take linear algebra
