If the section is a review section, this mostly applies to problems in the first chapter, there will probably not be as much detail to. The level of detail in each solution will depend up on several issues. Brachistochrone problem The classical problem in calculus of variation is the so called brachistochrone problem1 posed (and solved) by Bernoulli in 1696. The problem above can be seen as an optimisation problem in inn-itely many variables (one for each t t 0,t 1). Some solutions will have more or less detail than other solutions. BASICS OF CALCULUS OF VARIATIONS MARKUS GRASMAIR 1. Bruce van Brunt is Senior Lecturer at Massey University, New Zealand. Here are the solutions to the practice problems for my Calculus I notes. Calculus of Variations Andrew Hodges Lecture Notes for Trinity Term, 2016 1 Stationary values of integrals This course on the Calculus of Variations is a doorway to modern applied math- ematics and theoretical physics. The book can be used as a textbook for a one semester course on the calculus of variations, or as a book to supplement a course on applied mathematics or classical mechanics. The text contains numerous examples to illustrate key concepts along with problems to help the student consolidate the material. In addition, more advanced topics such as the inverse problem, eigenvalue problems, separability conditions for the Hamilton-Jacobi equation, and Noether's theorem are discussed. The fixed endpoint problem and problems with constraints are discussed in detail. The book focuses on variational problems that involve one independent variable. The mathematical background assumed of the reader is a course in multivariable calculus, and some familiarity with the elements of real analysis and ordinary differential equations. This book is an introductory account of the calculus of variations suitable for advanced undergraduate and graduate students of mathematics, physics, or engineering. Much of the mathematics underlying control theory, for instance, can be regarded as part of the calculus of variations. More recently, the calculus of variations has found applications in other fields such as economics and electrical engineering. The calculus of variations has a long history of interaction with other branches of mathematics, such as geometry and differential equations, and with physics, particularly mechanics.
