Please see my comment here. I am unable to delete it since the X used to delete it overlaps with the Related question links:
Is there any way that I can delete the comment?
I can think of a couple of ways...
You can flag it and ask us diamond-mods to delete
You can disable MathJax, delete and then enable MathJax.
You may also find the formatting sandbox in meta.math.stackexchange to be useful when typing complex mathematics for a comment.
