Having problems solving this diff equation.
(1-x^2)y´+ xy = x for -1 < x < 1
I get the ínt factor to 1/(1-x^2)^0,5, But having problems after that.
Thank you.

Im sorry, I meant the left side =)
ok, so following the steps exactly, you would end up withQuote:

now integrate both sides and continue
look closely at the steps and see what is confusing you. the single derivative is simply the coefficient of y' times y.
Oh,, I did exatly that but I thought it was wrong. Thank you very much.
you're welcome :)Quote:

I messed up when I multiplied the coefficient of y' and y. I Do that to check that im on the right track but this time it turned out bad =(.
