since the differential at a point (for a differentiable function):formula_18is a linear map it has a well defined inverse if, and only if, "dfx" is a bijection.
; second remarksince the differential at a point (for a differentiable function): formula_4is a linear map, it has a well-defined inverse if and only if "dfx" is a bijection.

====spherical form====the potential "v"(r) at a point r outside the charge distribution, i.e., _r_ > "r"max, can be expanded by the laplace expansion,:formula_21where formula_22 is an irregular solid harmonic (defined below as a spherical harmonic function divided by "r""l+1") and formula_23 is a regular solid harmonic (a spherical harmonic times r"l").
