3.1 Suppose {n} and {y} are sequences of real numbers. Let {} be a sequence of complex numbers, defined by 2n = In +iyn. Show that the complex sequence converges when the two real sequences converges. (5) 00 3.2 Show that the complex series with = an+iy, converges if lim, n = 0. Other- wise it diverges. (5) 3.3 Show that the geometric series converges if q<1. Otherwise it diverges. (5)
