Question
$({\rm{cosec}}\,x\log y)dy + ({x^2}y)dx = 0$ का हल है
==> $\frac{1}{y}\log ydy = - {x^2}\sin xdx$
दोनों तरफ समाकलन करने पर,
$\frac{{{{(\log y)}^2}}}{2} + [{x^2}( - \cos x) + \int_{}^{} {2x\cos xdx} ] = c$
==> $\frac{{{{(\log y)}^2}}}{2} - {x^2}\cos x + 2(x\sin x + \cos x) = c$
==> $\frac{{{{(\log y)}^2}}}{2} + (2 - {x^2})\cos x + 2x\sin x = c$.
