Solve using method of variation of parameters
WebMar 31, 2016 · Since the right hand side is cos ( 2 x) + 1, "undetermined coefficients" works much more simply. Look for a solution of the form. y ″ + y = − 4 A cos ( 2 x) + A cos ( 2 x) + B = − 3 A cos ( 2 x) + B = cos ( 2 x) + 1. Take A = − 1 / 3 and B = 1. You should remind yourself how variation of parameter works. http://mathonline.wikidot.com/the-method-of-variation-of-parameters-examples-1

WebExpert Answer. T …. Find a general solution to the differential equation using the method of variation of parameters. y'' + y = 5 sect The general solution is y (t) = 17. Find a general solution to the differential equation using the method of variation of parameters. y"' + 10y' + 25y = 2 e - 5t The general solution is y (t)=1. In mathematics, variation of parameters, also known as variation of constants, is a general method to solve inhomogeneous linear ordinary differential equations. For first-order inhomogeneous linear differential equations it is usually possible to find solutions via integrating factors or undetermined coefficients with considerably less effort, although those methods leverage heuristics that involve guessing and do not work for all inhomogeneous linear …
