The diff: equation corresponding to y2 - 2ay + x2 = a2 by eliminating a is
(dy/dx)2 (x2 - 2y2) - 4 (dy/dx)xy - x2 = 0
(dy/dx)2 (y2 - 2x2) - 4.dy/dx . xy - x2 = 0
(dy/dx)2 . y2 - 4. dy/dx . xy - x2 = 0
(dy/dx)2(x2 - 2y2) - 4. dy/dx - x2 = 0
The solution of the equation (x + 1)2. dy/dx = xex is
(x + 1) y = (x + 1)ex + c(x + 1)
(x + 1)y = (x + 1)ex + c
(x + 1)y = ex + c(x + 1)
y = (x + 1)ex + c (x + 1)
tan-1x + tan-1y = c is the general solution of the differential equation
(1 + x2)dy + (1 + y2)dx = 0
An integrating factor of the diff: equation (1 + y + x2y) dx + (x + x3) dy = 0 is
