Using the homotopy method to find periodic solutions of forced nonlinear differential equations This paper discusses a result of Li and Shen which proves the existence of a unique periodic solution for the differential equation x + k á + g(x,t) = (t)... TH Fay,PA Lott - 《International...
To find the quantity of interest as a series expansion in a small parameter is the basic tenet of perturbation theory [3–7]. The obvious in the perturbation method flaw is that we frequently have no interest in the big parameter domain of the theory being investigated. Several solutions ...

How to Find the Period of a Cosine Function Other sinusoidal waves can be described as transformations of the parent cosine function. The general form of a cosine function can be expressed as $$y = A \cos \left((B(x-C)\right) + D $$Applications...
where ω is usually chosen to be a number between 1 and 2; however, it is often necessary to experiment to find a value that is close to optimum. For systems in which the matrix A is symmetric, positive definite, and relatively sparse, a class of methods based on the minimization of ...

The method for solving linear first order equations is to rewrite the left-hand side of Eq. (3) as a derivative of a product of y with another function. To this end we find a function r(x) such that This is the left-hand side of Eq. (3) multiplied by r(x). So multiplying Eq...
