Solution of $\frac{d y}{d x}=\frac{x \log x^2+x}{\sin y+y \cos y}$ is
Solution of $\frac{d y}{d x}=\frac{x \log x^2+x}{\sin y+y \cos y}$ is
- $y \sin y=x^2 \log x+C$
- $y \sin y=x^2+C$
- $y \sin y=x^2+\log x$
- $y \sin y=x \log x+C$
Solution
We have,
$\frac{d y}{d x}=\frac{x \log x^2+x}{\sin y+y \cos y}$
$\Rightarrow(\sin y+y \cos y) d y=\left(x \log x^2+x\right) d x$
On integrating both sides, we get
$-\cos y+y \sin y+\cos y$
$=\frac{x^2}{2} \log x^2-\frac{x^2}{2}+\frac{x^2}{2}+C$
$\Rightarrow \quad y \sin y=\frac{x^2}{2} \log x^2+C$
$\therefore \quad y \sin y=x^2 \log x+C$
