Integration §1.The Riemann Integral Let a and b be two real numbers with a < b.Then [a;b] is a closed and boundedinterval in IR. By a partition P of [a;b] we mean a finite ordered set {t0;t1;:::;tn} such that a = t0 < t1 < ··· < tn = b: The norm of P is defined by ∥P∥:= max{ti − ti−1: i = 1;2;:::;n}. Suppose f is a bounded real-valued function on [a;b].
