    <p>
      The function u(x) is to be solved for in the equation:
      <blockquote>
        u * du/dx = nu * d^2u/dx^2
      </blockquote>
      for 0 &lt; nu, a &lt;= x &lt;= b.
    </p>

    <p>
      Problem data includes the endpoints a and b, the Dirichlet boundary values
      u(a) = alpha, u(b) = beta, and the value of the viscosity nu.
