Webx iy x iy = x iy (x+ iy)(x iy) = x iy x2 + y2 (2) The expression x iyappears so often and is so useful that it is given a name: it is called the complex conjugate of z = x+ iy, and a shorthand notation for it is z; that is, if z = x+ iy, then z= x iy. For example, 3 + 4i= 3 4i, as illustrated in Fig 1a . Note that z= zand z 1 + z 2 = z 1 + z 2. WebTwo complex numbers z 1 = x 1 + iy 1 and z 2 = x 2 + iy 2 are equal if and only if x 1 = x 2 and y 1 = y 2. Or Re (z 1) = Re (z 2) and Im (z 1) = Im (z 2). Calculation: Given: (1 + i) (x + iy) = 2 + 4i. ⇒ x + iy + ix + i 2 y = 2 + 4i. ⇒ (x – y) + i(x + y) = 2 + 4i. ...
