Statement :
\If a function is
is a solution of differential equation, then
is also a solution of
.
Consider a differential equation
.
Let the function is of the form
.
Consider a function
.
Substitute
in
.
Check whether the function
is a solution of a first order differential equation
or not.
Consider
.
Differentiate with respect to
.

Substitute

Since the above statement is true, the function
is a solution of first order differential equation
.
Let the function is of the form
, where
is a constant value.
Consider
.
Substitute
and
in
.

Check whether the function
is a solution of a first order differential equation
or not.
Consider
.
Differentiate with respect to
.

Substitute
and
in
.

Since the above statement is false, the function
is not a solution of first order differential equation
.
Therefore, the function
is a solution of first order differential equation
.
Theerfore, the statement is false.
\The statement is false.
