It can be shown that this substitution leads to the following equation, which is a separable equation that is readily solved for the derivative v'(x) of v(x). Integration of v'(x) then gives the desired (nonconstant) function v(x). O E. -2x xe F. xe 2x Y,v' + (2y, + Py1)v =0 A differential equation and one solution y, is given below.
