I have a question of show that y=x is one solution of the equation (1+x^2)y''-2xy'+2y=0) this is a question that i need to know for a coming exam. i understand and can do everything until the question gets to v''+(2/x(1+x^2))v'=0
then the question skips to IF =e^integral of (2/x(1+x^2))dx. what does this mean and where does it come from
