Let a and b be integers, and let Use the Division Algorithm toprove that if c is a common multiple of a and b, then m divides c.

L31 - 3 For anyn, R n As n →∞ ,w atpesoorpoitn We deﬁne the area an→∞imn 4 √ √ √ √ =in→∞ n [ x1 + x 2 ... + xi+ ... + xn] Similarly, we can also deﬁne the n→∞a ns ln→∞L on lim M , where L is the left endpoint approximation and M is the n n midpoint approximation (see page 290 of the text).
