If `y+d/(dx)(x y)=x(sinx+logx),fin dy(x)dot`

Text Solution

Verified by Experts

The given differential equation can be written as `` `x frac{d y}{d x}+2 y=x(sin x+log x)`
`rightarrow quad frac{d y}{d x}+frac{2}{x} cdot y=sin x+log x`
`` which is linear in y i.e. of the type `frac{d y}{d x}+P y=Q`
Hence `P=frac{2}{x}`
`` ...
