Question 1195105
.


Yesterday,  I noticed in my post  (see the link below),  that formula  # 3  is written incorrectly in your post.


Today you copied and posted it without any change.



My impression is that you have no any interest to what is written in your post,
as well as to what is written in my post.



I am in doubt if you read,  at all,  what is written there, 
and all your job with the problem is copy-paste it from one site to another.
