This category contains pages concerning Definite Integral is Area:
Let $f : \closedint a b \to \R$ be Darboux integrable over $\closedint a b$.
Let $A$ be the total signed area between $\map f x$ and the $x$-axis, and between the lines $x = a$ and $x = b$.
Then $A$ equals the Darboux integral of $f$ over $\closedint a b$.
