Verify the following relations for cylindrical coordinates u = r, v = 0, w = z:
a) the surfaces r = const, 0 = const, z = const form a triply orthogonal family, and
a(x, y, z)
=r;
a(r, 0, z)
b) the element of are length is given by
ds? = dr² +r²d0² + dz?;
c) the components of a vector p are given by
P, = Px cos 0 + py sin 0,
Po = -Px sin 0 + Py cos 0, P: = P2i
d) grad U has components: aU làu aU.
