9. Using Generalized Curvilinear Coördinates, if the scalar S and the vector Ä are both functions of position, prove the following relations: (a) 7 (SA)=s(8. A)+A.IS; (b) (x(SA)=s(0xĂ)+()xA; (c) Ex(s)=0; (a) 8x(0xA)=(. A)-VA. Most of these identities are independent of the specific coördinate system that one employs; however, care must be taken with the operator VA, since in Cartesian Coördinates, it is defined as G?A=i(v?4)+1(v24,)+R(v?4.), but in the Cartesian case, the unit vectors are independent of the coordinate variables, which...
