Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

Question

I have solved the problem from the diagram in the book and I want to know whether the solution is correct or not.

(A) Draw a sketch of a typical CL vs angle-of-attack curve and a CD vs CL curve, and show how
increasing camber (by putting a flap down) would change these curves.
(B) Draw the same curves, and show how using boundary-layer control or leading-edge devices
would change these curves

B.
