1.General solution of the differential equation x dyx2+y2+(1−yx2+y2)dx=0\frac{x\,dy}{x^2 + y^2} + \left(1 - \frac{y}{x^2 + y^2}\right)dx = 0x2+y2xdy+(1−x2+y2y)dx=0 isa.x+tan−1(yx)=cx + \tan^{-1}\left(\frac{y}{x}\right) = cx+tan−1(xy)=cb.x+tan−1(xy)=cx + \tan^{-1}\left(\frac{x}{y}\right) = cx+tan−1(yx)=cc.x−tan−1(yx)=cx - \tan^{-1}\left(\frac{y}{x}\right) = cx−tan−1(xy)=cd.none of theseLogin to continueOnly logged in users canattempt or see the solution.
