What is the solution of the differential equation y d x-x d y y^2 =0 ? where c is an arbitrary constant.
Options
- Ax y=c
- By=c x
- Cx+y=c
- Dx-y=c
Correct answer
B. y=c x
Step-by-step solution
y d x-x d y y^2 =0 aligned & y d x-x d y=0 & d y y = d x x aligned Now integrating both sides, aligned & d y y = d x x & y= x+ c & y= c x & y=c x & Option (B) is correct. aligned
