MCQ
$x\,dy + y\,dx - \sqrt {1 - {x^2}{y^2}} dx = 0$ નો ઉકેલ મેળવો.
- A${\sin ^{ - 1}}xy = c - x$
- ✓$xy = \sin (x + c)$
- C$\log (1 - {x^2}{y^2}) = x + c$
- D$y = x\sin x + c$
$\frac{{dxy}}{{\sqrt {1 - {{(xy)}^2}} }} = dx$.
Integrating both side, we get
${\sin ^{ - 1}}xy = x + c$ ==> $xy = \sin (x + c)$.
