A definite integral computes the exact area between a function f(x) and the x-axis over a closed interval [a, b]. Unlike an indefinite integral, it produces a specific numerical value rather than a function plus a constant. Notation: $$\int_{a}^{b} f(x)\,dx = F(b) - F(a)$$ where F(x) is any antiderivative of f(x), and a and b are the lower and upper limits of integration respectively. Definite Inte...
