[Hint: For the rst integral integrate exp( az ) = (exp( z ) + 1) around a rectangle with vertices at R , R , R +2 i and R +2 i . The second integral can be obtained similarly, or deduced from the rst.] 4. (30 pts.) Obtain the formulae (a) (15 pts.) Z 1 1 1 cos( x ) x 2 dx = , (b) (15 pts.) Z 1 sin( x ) x (1 x 2 ) dx = .
