NonConstants
NonConstants
is an option for
D
which gives a list of objects to be taken to depend implicitly on the differentiation variables.
MORE INFORMATION
If
c
does not appear in the list of
NonConstants
, then
D
[
c
,
x
]
is taken to be
0
unless
c
and
x
are identical expressions.
EXAMPLES

Basic Examples
(1)
Here
c
is treated as a constant under differentiation:
In[1]:=
Out[1]=
Specify that
c
depends implicitly on
x
:
In[2]:=
Out[2]=
Specify that both
c
and
d
depend implicitly on
x
:
In[3]:=
Out[3]=
