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.
