Describe the mapping properties of w z 1 z
WebTo see this, define Y to be the set of preimages h −1 (z) where z is in h(X). These preimages are disjoint and partition X. Then f carries each x to the element of Y which contains it, and g carries each element of Y to the point in Z to which h sends its points. Then f is surjective since it is a projection map, and g is injective by definition. http://academics.wellesley.edu/Math/Webpage%20Math/Old%20Math%20Site/Math208_310sontag/Homework/Pdf/hwk7a1_solns.pdf

Web1 w z which looks a lot like the sum of a geometric series. 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 ... WebSep 2, 2016 · 1 With these type of problems, you basically see if the image of the function provides a surjection into a nice region. In this case, we want to show that f ( z) = z 3 "hits" every point of the disk centered at the origin with radius 8 in the image space. Indeed, this is the case, take w ∈ D ( 0, 8) w = r e i θ = f ( z) 0 ≤ r < 8
