Question: The solution of the differential equation \(x \left( e ^ { 2 y } - 1 \right) d y + \left( x ^ { 2 }...
The solution of the differential equation
x(e2y−1)dy+(x2−1)eydx=0is
A
ey+e−y=logx−2x2+c
B
ey−e−y=logx−2x2+c
C
ey+e−y=logx+2x2+c
D
None of these
Answer
ey+e−y=logx−2x2+c
Explanation
Solution
x(e2y−1)dy+(x2−1)eydx=0
⇒ ∫eye2y−1dy=∫x1−x2dx⇒ ey+e−y=logx−2x2+c.
