Could you build this?
No Formalizing hundreds of complex calculus theorems and problems across an entire standard textbook into Lean 4 requires deep graduate-level mathematical rigor and specialized interactive theorem proving skills.
What it would actually take: This project requires advanced formal verification in Lean 4 and Mathlib. The builder must translate informal mathematical prose and epsilon-delta proofs into strict dependent type theory, manually guiding tactics and dealing with complex real analysis formalizations where automated theorem provers and current LLMs frequently fail or hallucinate invalid proof steps.
