Hi, I am having a little trouble solving a linear equation:(adsbygoogle = window.adsbygoogle || []).push({});

[tex] y' cosx = ysinx + 2x [/tex]

I translated it into standard y' + P(x)y= Q(x) format as

[tex]y' - ytanx = 2x/cosx [/tex]

then I needed an integrating factor, so I used

[tex]I(x)=e^{-\int tanx\:dx} = cosx[/tex]

when I multiply this to both sides of [tex]y' - ytanx = 2x/cosx [/tex]

it doesn't seem to do much good. I just get back to where I started, and I am not seeing anything that will wrap into a nice neat little derivative on the LHS.

Can you show me where I am going wrong? Thanks!
