Handout Four: Differential Calculus on Surfaces
نویسنده
چکیده
We have just finished our study of plane and space curves, or, if you like, of vectorvalued functions of a scalar variable. The next unit of the course focuses on the differential calculus of surfaces in three-dimensional space: these include the case of scalar-valued functions of a vector variable, i.e., z = f(x, y). It turns out that that surfaces in R are most analogous to curves in the plane (and not to curves in

An analytic study on the Euler-Lagrange equation arising in calculus of variations
The Euler-Lagrange equation plays an important role in the minimization problems of the calculus of variations. This paper employs the differential transformation method (DTM) for finding the solution of the Euler-Lagrange equation which arise from problems of calculus of variations. DTM provides an analytical solution in the form of an infinite power series with easily computable components. S...
متن کاملThe Effects of Different SDE Calculus on Dynamics of Nano-Aerosols Motion in Two Phase Flow Systems
Langevin equation for a nano-particle suspended in a laminar fluid flow was analytically studied. The Brownian motion generated from molecular bombardment was taken as a Wiener stochastic process and approximated by a Gaussian white noise. Euler-Maruyama method was used to solve the Langevin equation numerically. The accuracy of Brownian simulation was checked by performing a series of simulati...

متن کاملDifferential geometry of curves and surfaces
These are two books that together in a pair are intended to bring the reader through classical differential geometry of curves and surfaces into the modern differential geometry of manifolds. The first book, Differential Geometry of Curves and Surfaces, by Thomas Banchoff and Stephen Lovett, offers a complete guide for the study of classical theory of curves and surfaces and is intended as a te...
متن کاملSOME FUNDAMENTAL RESULTS ON FUZZY CALCULUS
In this paper, we study fuzzy calculus in two main branches differential and integral. Some rules for finding limit and $gH$-derivative of $gH$-difference, constant multiple of two fuzzy-valued functions are obtained and we also present fuzzy chain rule for calculating $gH$-derivative of a composite function. Two techniques namely, Leibniz's rule and integration by parts are introduced for ...
