Question

express the unit vectors (𝑟̂, đťśĚ‚,𝜙̂) in spherical polar coordinates in terms of the unit vectors (đť‘–Ě‚,đť‘—Ě‚, đť‘Ě‚) in the cartesian coordinate system. invert these equations to express the unit vectors (đť‘–Ě‚,đť‘—Ě‚, đť‘Ě‚) in the cartesian coordinate system in terms of the unit vectors (𝑟̂, đťśĚ‚,𝜙̂) in the spherical polar coordinate system.
