14.7 Day 2 Triple IntegralsUsing Spherical Coordinates

and more applications of cylindrical coordinates

This is a Klein bottle, It is a 4 dimensional objected depicted here in 3 dimensions

This object has only 1 side.

More information about the Klein bottle can be found at

Conversions between Spherical and other Coordinate systems

Converting the differential(finding the Jacobian)

dxdydz=ρ sinφ dρdφdθ 2

Why? To find volume of the box at the left, use V=lwhV = dρ * ρdφ * rdθ(the r is from cylindrical coordinates)

From chapter 11r = ρsin φ

Hence dxdydz=ρ sinφ dρdφdθ
