Solution
The correct option is
A
True
A differential equation of the form
d
y
d
x
=
f
(
x
,
y
)
if
f
(
t
x
,
t
y
)
=
t
0
f
(
x
,
y
)
=
f
(
x
,
y
)
Here,
d
y
d
x
=
−
1
−
e
x
y
e
x
y
(
1
−
x
y
)
So,
f
(
x
,
y
)
=
−
1
−
e
x
y
e
x
y
(
1
−
x
y
)
which satisfies
f
(
t
x
,
t
y
)
=
f
(
x
,
y
)
So, the given equation is
homogeneous.
