Your Mathematica code appeared in unreadable form.

Try repost it BUT this time select the cells (both inputs & outputs)
and press
Shif+Ctrl+I (simultaneously!) in order to convert everything to
InputForm. Then
select the "Copy as Plain Text". Also try to avoid the use of special
characters
like greek letters when you post to the forum. I think if you follow
this advice
we can see your equations!
