If (2+ x) d y ~d x +(y+1) x=0 and y(0)=1 , then y ( 2 ) is equal to
Options
- A- 2 3
- B- 1 3
- C4 3
- D1 3
Correct answer
D. 1 3
Step-by-step solution
array ll & (2+ x) d y ~d x +(y+1) x=0 & 1 y+1 ~d y= - x 2+ x ~d x & Integrating on both sides, we get & (y+1)=- (2+ x)+ c & When x=0, y=1 & c =2 2= 4 & (i) (y+1)=- (2+ x)+ 4 & (y+1)= ( 4 2+ x ) array aligned & y+1= 4 2+ x & y= 4 2+ x -1 & y ( 2 )= 4 3 -1= 1 3 aligned
