It also made use of the Euler and Runge-Kutta method to solve initial value problems in order to compare the performance of the two methods Tue, 01 Sep 2015 00:00:00 GMT http://repository.fuoye.edu.ng:80/handle/123456789/1334 2015-09-01T00:00:00Z http://repository.fuoye.edu.ng:80/handle/123456789/1118 Title: A STUDY AND THE USE OF LAGRANGE MULTIPLIER IN CALCULUS OF VARIATION Authors: ABDULYEKEEN, KHADIJAT OLUWAKEMI Abstract: This project work examines the use of Lagrange multipliers to calculus of variation (isoperimetric problem). Basic definition of terms were given, necessary and suficient condition for a function to be maxima or minima, how to identify Lagrange multipliers in any given problem and general usage of largange multipliers, Lagrange multiplier in unconstraint and constraint problems, theorems and proof related to Lagrange multipliers. Literature review, Euler's Multiplier rule and isoperimetric problem, proof's motivated by Euler and Lagrange, the power system economic operation. Methods of solving Lagrange function, i also included derivation of Euler-Lagrange equation and other form's of Euler equation,extremal,calculus of variation, isoperimetric problems and method for solving extrema of a given function (minimum and maximum) were examined. Numerical examples were provided. Fri, 15 Jan 2016 00:00:00 GMT http://repository.fuoye.edu.ng:80/handle/123456789/1118 2016-01-15T00:00:00Z
