Consider a very thin vertical strip The lenght of the strip B : Y.-Y or (c-x2) - (-x) Since the widht of the strip is very small Y: - X change in x we could call it dx is Y I Since the ship is long shin rectangle. the area dx - Yes Y2 of the strip is Y2 Length. width I (2-x + x) dx le We add all the strips we gel 2-X +x dx 5 2-x + x dx 2x I x3 2 -1 3 2 3 8 ( 32 +' 6-8 + 2 The formula for the 3 3 2 area between curves is: 36-16-12-2-3 : 6 Area : f.(x) - fz(x) dx - 27 6 We will us this so much that = a we won't need to Memorize 2 the Formula
