Solution of the differential equation $\frac{\text{dy}}{\text{dx}}+\frac{\text{y}}{\text{x}}=\sin\text{x}$ is:
$\text{x}(\text{y}+\cos\text{x})=\sin\text{x}+\text{c}$
$\text{x}(\text{y}-\cos\text{x})=\sin\text{x}+\text{c}$
$\text{x}\text{y}\cos\text{x}=\sin\text{x}+\text{c}$
$\text{x}(\text{y}+\cos\text{x})=\cos\text{x}+\text{c}$
