Exercise 111.43.2. Let $A$ be a ring. Let $I = (f_1, \ldots , f_ t)$ be a finitely generated ideal of $A$. Let $U \subset \mathop{\mathrm{Spec}}(A)$ be the complement of $V(I)$. For any $A$-module $M$ write down a complex of $A$-modules (in terms of $A$, $f_1, \ldots , f_ t$, $M$) whose cohomology groups give $H^ n(U, \widetilde{M})$.
