Problem 7: Prolate spheroidal coordinates {0 <n<∞0,0<0 < T, 0<¢ < 2n} are described by the
metric coefficients
h1 = h2 = a?(sinh? 7 + sin? 0)
h3 = a? sinh? nsin? 0
where a is a constant. Derive Laplace equation and separate it into three ODESS. Don't solve the separated
ODES.

Problem 6: Two spherical conductors of radii a and b (b > a). The sphere of radius r = a is held at a
potential f(0), and the sphere of radius r = b is held at a potential g(0). The problem of the potential
between the two spheres, denoted by u(r, 0), can be described by
