Question 1200335
.


If you want to learn a subject, it is the WORST possible strategy 
to post many twin problems of the same type at a time, as you did it today.



It only irritates the tutors and GUARANTEED that you will get a detailed solution 
to NO ONE of your numerous problems.



Much better strategy is to request ONE typical problem; maximum two at a time.



Then you are GUARANTEED that you will get an adequate answer 
and will have a valuable material to start thinking/doing on your own.



When you post 5 - 7 twins/(same type) problems, you simply work against yourself.


        you simply work against yourself.


                you simply work against yourself.


                        you simply work against yourself.
