WebSubsection 3.1.3 Area Between Curves: Integration w.r.t. \(x\). We have seen how integration can be used to find an area between a curve and the \(x\)-axis. With very little change we can find some areas between curves; indeed, the area between a curve and the \(x\)-axis may be interpreted as the area between the curve and a second “curve” with equation \(y=0\text{.}\) WebSep 25, 2015 · This leads to a very simple algorithm for computing the centroid, based on a sum of triangle centroids weighted with their signed area. The triangles can be taken to be those formed by any fixed point, e.g., the vertex v0 of the polygon, and the two endpoints of consecutive edges of the polygon: (v1,v2), (v2,v3), etc.
