The derivative of ln|x| is an odd function
is it true/false
Solution: The given function can be written as:
Taking derivative of the above, we get:
Note that at
,
is not defined. Therefore, we get:
where,
.
Now we test the function whether it is odd or not.
Let
be denoted by
. It will be odd if it satisfies the following condition:
Now,
or,
and, we know:
Comparing (1) and (2), we get:
Therefore, the derivative of
is an odd function.
