A laminar boundary layer velocity profile is approximated by \(u / U=[2-(y / \delta)](y / \delta)\) for \(y \leq \delta\), and \(u=U\) for \(\mathrm{y}>\delta\).

(a) Show that this parabolic profile satisfies the appropriate boundary conditions.

(b) Use the momentum integral equation to determine the boundary layer thickness, \(\delta=\delta(x)\). Compare the result with the exact Blasius solution.
