So, what did you try?

given that z = x + iy,

modulus(e^xt*e^iyt)/modulus (t + 1). Since Re(z) < 0, e^xt --> 0. Does this show that the integral has a finite limit? - May 7th 2011, 03:16 PMshaheen7
also Morera's theorem states that f should be continuos and int(f) = 0. Does the above e^xt --> 0 show int(f) = 0, or do we have to solve the integral?

i suppose f is not discontinuous on S? - May 8th 2011, 12:13 AMJose27

i'm a bit confused as to how you got e^-ct. did you get that by integrating the function?
