Part 1 Fundamental Theorem
|
Let f(t) be continuous on interval [a, b]
Let A(x) = ∫ [a, x] f(t) dt where x is in [a, b] then A'(x) = f(x) Example: F(x) = ∫ [x, π] (t + 1) dt = - ∫ [π, x] (t + 1) dt F'(x) = x + 1 |
|
Part 2 Fundamental Theorem
|
Let f(t) be continuous on interval
[a, b] and let F(t) be an antiderivative for f(t), then ∫ [a, b] f(t) dt = F(b) - F(a) |
