Evaluate (x² + y) dA, given that R is the region inside a triangle with vertices (0.0), (1.1), and (1,-1). A lamina is a sector of a circle radius r with an angle ß as shown in Figure 1. Figure 1 If the lamina has constant density, use double integral in polar coordinates to answer the followings: (i) Show that the area of the lamina is r² B. (B in radians). (ii) Find the centroid of the lamina. (Transform the integral √12 MM √12-x² √2 √16-x²-y2 into each of the following coordinates systems: (i) cylindrical, dz dy dx (ii) spherical.
