**Fundamental theorem of calculus-1**, strict differentiability in both endpoints. If `f : ℝ → E` is integrable on `a..b` and `f x` has finite limits `ca` and `cb` almost surely as `x` tends to `a` and `b`, respectively, then `(u, v) ↦ ∫ x in u..v, f x` has derivative `(u, v) ↦ v • cb - u • ca` at `(a, b)` in the sens...
