1 4.2 Area Definition of Sigma Notation = 14

2 Summation Properties 1. k is a constant 2.

3 Summation Formulas 1. 2. 3. 4.

4 Evaluate the sum for n = 10, 100, 1,000, and 10,000 First, factor out the 1/n2 n

5 For n = 10 .65 100 .515 1,000 .5015 10,000 .50015

6 Find the

7

8 Using Upper and Lower Sums to Find Area (Rectangles)
Find the approximate area of the region bounded by y = x2, y = 0, x = 0, and x = 2. Let n = 4 be the number of rectangles. Lower Sum 4 = 1.75

9 Upper Sum 4 = 3.75 The area must be between

10 Now, let n = an infinite number of rectangles
f(x) = x2 base x height
