Angle of Rotation using area moment method

Do you have any sample problem in solving for the angle of rotation in the deflection of the beam at any point using area moment method? Thanks :)

The area-moment method is suitable for finding the rotation of a "specific" point on the beam not at "any" point. And note also that the rotation found using area-moment method is a relative rotation, for it is a rotation between two tangents. Double integration method is more appropriate if you wish to find the rotation of beam at any point.
