Corrections to upcoming seminars

So here I was evidently too careless writing it all up, and having been sleepless with term papers, I discovered errors only during the workshop ... :-( Corrections made in the seminar assignments document: 

• A nonsensical sentence about 81 "(a)", and there is no "(a)", I meant only the first integral.
• 100 (b) requires a hint to even be curriculum. Sorry.
• 2015#3, which 2015? I intended spring. Suggest to give this least priority then.
