Solution 16.
See text and/or instructor's solution manual.
Solution. For starters Theorem
3.8 states that both the real and imaginary part of an
analytic function is a harmonic function.
As illustrated in Exercise 5, if v(x,y) is
harmonic in a suitable domain D, then
it is possible to construct a harmonic
function u(x,y)
so that v(x,y) is
harmonic conjugate of u(x,y) and
is
an analytic function the D.
