I dont know why ?
Whenever I find difficulties concerning my studies, I post them here in italki, But I only recieve coments investigating me, if it is an exam question or something else. Just to make it clear, I have never rely on anyones answer on my examination. And its obvious that we dont know the exam questions till the day we will take them. I have professors that won't hesitate to give Zero as a mark, in case they found same answer in internet. For exampl, I have read an articl lately, and I found some questions under it, that were too hard for me to understand. So I posted them here in iTalki hoping to understand well and enlarge my knowledges, but I only get replies out of the point.
Could someone please show me how to proves.

Hi. I'm not certain I understand your question. But I do have a comment to make. I'm glad that you explained how you use this forum. It sounds as if you're  using it in an honest manner for your edification. That's commendable.
What bothers me are the persons who post what is clearly an assignment. And they do it repeatedly, multiple times a day. I've stopped answering those queries. So thanks again for your explanation. I'm curious to see what others have to say.
