Unformatted text preview: x + h ( y ) y = y = x + h ( y ) Comparing this to: N =4 y + x h ( y ) =4 y h ( y ) = 2 y 2 + C The nal answer becomes: 3 x 3 + xyx2 y 2 = C 16.) ( ye 2 xy + x )d x + ( bxe 2 xy )d y = 0 M y = ( ye 2 xy ) y = e 2 xy + 2 xye 2 xy N x = ( bxe 2 xy ) y = be 2 xy + 2 bxye 2 xy Equation is exact if b = 1. Using M to solve (and integrating by parts): = Z M d x = Z ( ye 2 xy + x )d x = 1 2 e 2 xy + 1 2 x 2 + h ( y ) y = y = xe 2 xy + h ( y ) Comparing this to: N = xe 2 xy h ( y ) = 0 h ( y ) = C 3 The answer becomes: 1 2 e 2 xy + 1 2 x 2 = C We can also multiply both sides by 2 and change 2 C C to get the answer in the form: e 2 xy + x 2 = C 4...
