parallel conditions for the validity of this formula?
30. Explain the meaning of astronomical azimuth reduction.
31. What is the function of Laplace azimuth in the triangulateration network?
32. Explain the concepts of solutions of the direct and inverse geodetic problems.
33. Explain the basic principles of the point-by-point integration for solutions of
direct geodetic problems.

problems.
35. Derive the relationship between the reduced latitude and the geodetic latitude.
36. Prove that in Bessel's solution of the geodetic problem, the azimuth of a
geodesic remains unchanged after projection.
