In addition to being intrinsically (thực chất) interesting, calculus of variations constitutes (tạo thành) an area that has been extensively considered in both theoretic (lý thuyết) and applied areas, underlying a large number of structures and phenomena (hiện tượng), including the stationary action principle in physics.
After defining the problem, and presenting some brief historic remarks, we proceed to present a motivational example of calculus of variations respective to a specific type of variation function, namely second-order polynomials adhering to the boundary conditions.
This chapter presents the basic theory of Calculus of Variations applied to fundamental (cơ bản) types of variational problems with applications in Physics and Engineering.
The calculus of variations is not really a coherent (mạch lạc) branch of mathematical theory. It’s rather, a category of mathematics problems.
