1. The problem statement, all variables and given/known data Find the solution of the differential equation yy'(1+x2)-x(1+y2)=0 if y(0)=Sqrt(3) 3. The attempt at a solution I let y=Sqrt(3) and x=0 and solve for y'. y'=0 Integrate both sides. y=x +c Plug my points in to find C Sqrt(3)=0 +c C=Sqrt(3) My solution is y=x+Sqrt(3). Check: Plug x+Sqrt(3) in for y, and 1 for y' into the DE. End up with Sqrt(3)=0, so somewhere I went wrong. Any help appreciated, Thanks.
