======================



<U>Comment from student</U>: You provided the model function but didn't explain how you do it.



<U>My response</U>:


(1)  &nbsp;&nbsp;This model function is &nbsp;SELF-EXPLANATORY.  


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;It means that you should look in it and listen it, &nbsp;and the formula will tell you everything about itself.


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I specially left it without explicit explanations in order for your mind had a room for your independent thinking.



(2)  &nbsp;&nbsp;You provided your comment, &nbsp;but forgot to say &nbsp;" Thank you for your teaching ".


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;It is quite low level of communicating with a tutor (first basic rule of polite communication is violated).


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I am very disappointed to see so low level.
