Homework Statement
(x2+1)y"+(2-x2)-(2+x)y=x(x+1)2
given 2 associated homogeneous solution are: ex and 1/x
Homework Equations
this is a question from shaum's outline differential equations chapter on "variation of parameters"
The Attempt at a Solution
so here what i got...
yh=C1ex+C2(1/x)
and now I am trying to find particular solution of y:
v1'ex+v2'(1/x)=0
and
v1'ex+v2'(-1/x2)=x(x+1)2/(x2+1)and now I am stucked at solving v1' and v2' someone help please?
