comment An easy way to remember PEMDAS
Maybe you find BEDMAS easier to remember? Brackets, Exponentiation, Division, Multiplication, Addition, Subtraction. (I changed that from BODMAS [Brackets Off ...] to contain your inclusion of Exponentiation)

comment Complex integration using singularities
Yes, you can only use the theorem if its conditions are met, so any restrictions are perfectly acceptable. Later on you will be able to state the correct value of the integral for your special case ($|w|=1$) once you know how to compute it using the residue theorem. I suspect your lecturer will not expect you to consider the special case, but if you do know how to use the residue theorem then just evaluate that special case as well and put that in your answer ! Make sure to follow the instructions of the question carefully though - maybe they don't want you to consider that special case...

Sorry, I read your question incorrectly by forgetting your initial sentence after reading the last, which lead my thoughts down the wrong path !

That's why I made this community wiki. Just though it might give some background. And exercise my little grey cells !

Yes, that's correct - I've updated the proof to reflect this.
