What is dV in Cylindrical Coordinates? Recall that when integrating in polar coordinates we set dA = r dr d?. When viewing a small piece of volume
Détermination de E(r) par application du théorème de Gauss : Appliquons le théorème de Gauss à une sphère de centre O et de rayon r = OM.
One interpretation of dV/dr is that for a small increase in radius of ?r the volume of the sphere will increase by 4?r2?r. Since 4?r2 is the surface area of
A sphere centered at the origin with radius 2. Exercise 8 (x2 +y2) dV where E lies between the spheres x2 +y2 +z2 = 4 and x2 + y2 + z2 = 9.
