Unformatted text preview: - (1 + x 2 ) and integrate from x = -1 to x = 2. The area dA of a vertical strip is: dA = [(3 + x) - (1 + x 2 )]dx Method of horizontal strips We divide the area A into thin horizontal strips of height dy and consider two cases to calculate their width. Area A1: 1 < y < 2 The area dA of a horizontal strip is: Area A2: 2 < y < 5 The area dA of a horizontal strip is:...
