16.360 Lecture 14 • Today Orthogonal coordinate systems • The Cartesian (rectangular) coordinate system • The cylindrical coordinate system • The spherical coordinate system
16.360 Lecture 14 • Cartesian coordinate system z dl y x
16.360 Lecture 14 • Cartesian coordinate system z directions of area y x
z y x 16.360 Lecture 14 • Cylindrical coordinate system
z y x 16.360 Lecture 14 • the differential areas and volume
16.360 Lecture 14 Example: cylindrical area z 5 3 60 y 30 x
16.360 Lecture 14 • Spherical coordinate system
16.360 Lecture 14 • differential volume in Spherical coordinate system
16.360 Lecture 14 • Examples (1) Find the area of the strip (2) A sphere of radius 2cm contains a volume charge density Find the total charge contained in the sphere
