Centroid of a polygon (centroid of a trapezoid, centroid of a rectangle, and others) To calculate a polygon's centroid,G(Cx, Cy), which is defined by its n vertices(x0,y),(x1,y1), ...,(xn-1,yn-1), all you need to do is to use these following three formulas: ...
Evaluate \int \int_R e ^ { ( y - x ) ( y + x ) } d A where R is the region in the xy-plane bounded by the trapezoid with vertices (0, 1), (0, 2), (2, 0), and (1, 0). Find the value of the triple integrals \int \int \int_D \; xy \: dV...
