There is this lesson in pregrad i am attending , that one part is qft and the other is group theory and applications . The questions , are from the second part. I can rewrite it in black if that helps .

Hey , thanks for your answer ! Can I post a better picture maybe ? Because i really don't have time to learn Latex now . My test is on Monday and i am studying qft like a maniac. Thanks in advance .
