Fig. tk\ dV= dxdydz. (2) 2. Cylindrical coordinates. If the x and the y of the rectan-gular coordinates are replaced by polar coordinates r and 6 inthe plane XOY, and the z coordinate is retained with its original 386 MULTIPLE INTEGRALS … Fig. significance, the new coordinates r, 0, and z are called cylindri-cal coordinates. The formulas connecting the two systems ofcoordinates are evidently x = r cos 0, y — r sin 0, z — z. Turning to fig. 227, we see that z = z1determines a plane parallel to the planeXOY, that 0 = Qx determines a…
