I recently posted this question on MO. However, it quickly got downvoted and there was a comment which read that "MO is not for homework."
However, that question was not homework and I had not got any response on Math.SE and so I put it here. I am trying to self-study and learn things on my own.
Is it a bad practice to put questions here if you need clarification and are not able to find on Math.SE?
