WebFeb 21, 2015 · Describe the image of the set { z = x + i y: x > 0, y > 0 } under the mapping w = z − i z + i So from this mapping , I can see that a = 1, b = − i, c = 1, d = i thus a d − b c = i + i = 2 i ≠ 0 so this is a Mobius transformation. Solving for z I got z = i + i w 1 − w for w = u + i v, we have z = − 2 v + i ( 1 − u 2 − v 2) ( 1 − u 2) + v 2 Webthe bisector will be equidistant from z1 and z2, the equation of the bisector can be represented by z − z1 = z − z2 . For a given equation f(x,y) = 0 of a geometric curve, if we set x = (z + z)/2 and y = (z − z)/2i, the equation can be expressed in terms of the pair of conjugate complex variables z and z as f(x,y) = f

We will make frequent use of the following manipulations of this expression. 1 w z = 1 w 1 1 z=w = 1 w 1 + (z=w) + (z=w)2 + ::: (3) The geometric series in this equation has ratio z=w. Therefore, the series converges, i.e. the formula is valid, whenever jz=wj<1, or equivalently when ... WebDescribe the image of {z : Re(z) > 0} under z → w where w−1 w+1 = 2z−1 z+1 Solution: We now must solve for w where w−1 w+1 = u and u ∈ D(0;2). ... Construct a conformal map onto D(0;1) for {z : −1 < Re(z) < 1} Solution: The map f(z) = z + i sends the strip x + iy : −1 < y < 1 to x + iy : 0 < y < 2. The map g(z) = (π/2)z sends 0 ... Web1.
