The general solution of the differential equation d y d x + 1+ 2 y 1- 2 y =0 is given by
Options
- Ay+ x=c
- By- x=c
- Cx- y=c
- Dx+ x=c
Correct answer
B. y- x=c
Step-by-step solution
We have, d y d x + 1+ 2 y 1- 2 x =0 d y d x =- ( 1+ 2 y 1- 2 x ) d y d x =- 2 ² y 2 ² x ² y d y=- cosec ² x d x ² y d y+ cosec ² x d x=0 y- x=c
