Question
The solution of the differential equation (x + y) (dx - dy) = dx + dy is
Options
A.x + y = Cex+y
B.x - y = Cex-y
C.x + y = Cex-y
D.None
Solution
θ
put x + y = v
1 +
⇒ (1 + v) dv = - 2dx
+ v = - 2x + c
+ (x + y) = - 2x + c
put x + y = v1 +
⇒ (1 + v) dv = - 2dx+ v = - 2x + c + (x + y) = - 2x + cCreate a free account to view solution
