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) (3yx)y' = 3x+y
 I got H
d) y'  2y x =1
 I got L
e) (yx)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"!)
