Unformatted text preview: again). We have y 1 = e − x and y 2 = xe − x . Thus, we have to solve the equations: v ′ 1 e − x + v ′ 2 xe − x = 0 v ′ 1 (e − x ) + v ′ 2 ( e − xxe − x ) = e x Solving this gives v ′ 1 =xe 2 x and v ′ 2 = e 2 x . Then v 1 =xe 2 x 2 + e 2 x 4 and v 2 = e 2 x 2 . Then y p = v 1 y 1 + v 2 y 2 = e x 4 , as above. Bonus (1 pt.): What book is currently number one on the New York Times NonFction best seller list?
