    Post Classififying ODEs

    Can someone agree with what I've got, and if not mention briefly were I went wrong?

    Classify each of these equations type(s) (linear = L), (separable = S), (Homogeneous = H), (Neither of those = N)

    a) 2yy' = 3x
    - I got S,H

    b) 2xy'+3y=0
    - I got S,H,L

    c) (3y-x)y' = 3x+y
    - I got H

    d) y' - 2y -x =1
    - I got L

    e) (y-x)y' = 2xsin(y)
    - I got N

    Looks good to me.

    (Because I absolutely HAVE to find something to pick on, "N" should be "NONE of the above" rather than "neither of the above"!)
