An elementary method for obtaining general solutions to systems of ordinary differential equations	2021	20	.pdf	application/pdf	6972	403	86	Identifying y1 = y therefore gives the general solution of the Liénard equation (4.7) from the above pair of equations. To express (4.1) as a system of the form (1.1), define y1 = y and y2 = dy/dx, yielding dy1 dx = f1(x, y1, y2) = y2, dy2 dx = f2(x, y1, y2) = −g(x)y1.	cache/ejde-296.pdf	txt/ejde-296.txt
