Residues and Poles; Positively Oriented Boundary

5. Let Cn denote the positively oriented boundary of the square whose edges lie along the lines: {see attachment}, where N is a positive integer. Show that {see attachment}. then, using the factr that the value of this integral tends to zero as N tends to infinity, point out how it follows that: {see attachment} Please specify the terms that you use if necessary and clearly explain each step of your solution.
