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?
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?

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