Question 1063187
.
Hello,


I saw several assignments in this forum in last couple days offering to identify the wrong steps or the right steps 
in some proves or logical/calculation steps.


My opinion is that such problems are not the best way to study/to teach the subject.


Much better way is to prove statements directly on your own or by reading the solutions/the proves from reliable sources.


It is much better than to trace turns/bends/ of somebody's curve/curved thoughts.


My personal opinion.
