The calculus of variations is a field of mathematical analysis that uses variations, which are small changes in functions and functionals, to find maxima and minima of functionals: mappings from a set of functions to the real numbers. Functionals are often expressed as definite integrals involving functions and their derivatives. Functions that maximize or minimize functionals may be found using the Euler–Lagrange equation of the calculus of variations.

A simple example of such a problem is to find the curve of shortest length connecting two points. If there are no constraints, the solution is a straight line between the points. However, if the curve is constrained to lie on a surface in space, then the solution is less obvious, and possibly many solutions may exist. Such solutions are known as geodesics. A related problem is posed by Fermat’s principle: light follows the path of the shortest optical length connecting two points, where the optical length depends upon the material of the medium. One corresponding concept in mechanics is the principle of least/stationary action.

Many important problems involve the functions of several variables. Solutions of boundary value problems for the Laplace equation satisfy the Dirichlet principle. Plateau’s problem requires finding a surface of the minimal area that spans a given contour in space: a solution can often be found by dipping a frame in a solution of soap suds. Although such experiments are relatively easy to perform, their mathematical interpretation is far from simple: there may be more than one locally minimizing surface, and they may have non-trivial topology.

Maxima and Minima are one of the most common concepts in differential calculus. A branch of Mathematics called “Calculus of Variations” deals with the maxima and the minima of the functionals. The calculus of variations is concerned with the variations in the functionals, in which small change in the function leads to the change in the functional value. The first variation is defined as the linear part of the change in the functional, and the second part of the variation is defined in the quadratic part.

Functionals are expressed as the definite integrals which involve the functions and their derivatives. The functions that maximize or minimize the functionals are can be found using the Euler – Lagrange of the calculus of variations. These two Latin maxima and minima words basically mean the maximum and minimum value of a function respectively, which is quite evident.

The maxima and minima are collectively called “Extrema”. Here, we assume our function to be continuous for its entire domain. Before knowing how to find maxima and minima, we should first learn about derivatives. Assuming that you all know how to find derivatives, let us go ahead and learn about some curves.

**CSIR NET Exam Pattern 2020:**

NTA has released the CSIR NET Exam Pattern for all the five subjects. Candidates will have to pick any one subject and apply for the same. The CSIR UGC NET exam pattern and marking scheme are different for all the subjects.

- CSIR NET question paper for each subject is divided into three parts namely, Part A, Part B, Part C.
- All three sections are compulsory.
- There will be no break between the three sections.
- All 3 parts will have only Multiple Choice Questions (MCQs).
- The CSIR NET 2020 will be conducted for a total of 200 marks.
- The exam will be held for a duration of 3 hours.
