Calculus
Fundamental theorem of calculus
Differentiation and integration are inverses — the link that ties everything together.
Differentiation and integration are inverses — the deepest result in calculus.
Two parts
- Part 1: d/dx [∫ₐˣ f(t) dt] = f(x).
- Part 2: ∫ₐᵇ f(x) dx = F(b) − F(a), where F' = f.
