Theorem 14-2. (The Second Fundamental Theorem of Calculus) If is integrable on , where is some differentiable function, then .
Theorem 13-4. If then (in particular, the rhs makes sense iff the lhs does).
The Yet Unknown:
Convention. and if we set .
Theorem 13-4'. so long as all integrals exist, no matter how , and are ordered.
Theorem 13-5. If and are integrable on then so is , and .
