[5 pts.] 5. Evaluate the expression r , (2) where r is the position vector from the origin to the point r , using (i) Cartesian coordinates and (ii) spherical coordinates (cf. (6.32)). [3+2=5 pts.] 6. (a) Find the most general function f ( r ) of only the radial coordinate r = | r | such that ( f r ) = 0 except possibly at the origin r = 0. (b) Find the most general function g ( r,, ) such that ( g r ) = 0, again except possibly at the origin r = 0. [4+1=5 pts.] 7. Problems 10.1a,b,c,d. ( Curvature of a function ) [2+1+4+3=10 pts.] 8.
