Can you prove in detail the metric space symmetry condition of the discrete metric, I find myself writing that if d(x,y)=0 and x=y then y=x which means that d(y,x)=0. But I have to prove it in a detailed manner with explanation apparently. Thank you in advance.
17. Show that the function d is a metric whered(x, y) = |x − y| / (1 + |x + y|)
$d$ is a metric on $X$.Show that $\rho : X^2 \to [0,\infty)$ defined by\[\rho(x,y) = \frac{3d(x,y)}{2 + 3d(x,y)}\]is also a metric on \(X
Let (X,d) be a metric space. Define f: X x X -> Real Numbers by f(x,y) = d(x,y) / 1+d(x,y) . show that f is a metric on X.
If we have a space with a metric d and distinct points A, B define the circle with center A and radius AB as the set of all points C such that d(A, B) = d(A, C). This is precisely the usual definition of a circle, except that the distance measurement is not assumed to be the usual one. For this exercise, our space is the usual plane and our metric is the taxicab metric: d((x, y),(z, w)) = |x − z| + |y − w|. Give an example, with a picture, of two circles with specific centers and radii (give actual coordinates for the points involved) which are distinct and intersect in exactly two points.
If (X, d_{1}) and (Y, d_{2}) are metric spaces, we define d: (X × Y ) × (X × Y ) \rightarrow R by d((x_{1}, y_{ 1}),(x_{2}, y_{2})) = d_{1}(x, x′) + d_{2}(y, y′).Answer the following literals a) Prove that d is a metric b) If X = Y = R with d1 equal to the usual metric and d2 the discrete metric. Describe what the balls are like with the metric d on R^{2}
Let (R>0, d) be the metric space defined by d(x, y) =|log (y/x)|. This metric space is isometric to the Euclidean line E1, where an isometry E1 → (R>0, d) is given by x→ ex . proof that x→ ex is isometric.
Let H be the set of all points (x, y) in ℝ2 such that x2 + xy + 3y2 = 3. Show that H is a closed subset of ℝ2 (considered with the Euclidean metric). Is H bounded? Bear in mind I can't use facts about continous functions. So this is what I learned in this chapter: Balls/neighborhood centered at a point a consists of all points strictly within some radius r of the point. A set is open if every point in the set has a small ball around it that is contained in the set. A set is closed if its complement is open, and sequentially closed if every sequence in the set has all accumulation points in the set. We proved these are equivalent. A set is sequentially compact if every sequence in the set has accumulation points in the set. A set is compact if every cover by open sets has a finite subcover. Compact sets are sequentially compact. In the reals, compact, sequentially compact, and closed + bounded are equivalent.

Consider the closed rectangle R = [a,b] × [c,d] in ℝ2 (under the Euclidean metric).i. Explain why every horizontal line of the form [a,b] × {y} is compact.ii. Given any open cover Oλ of R, conclude that each line of the form [a,b] × {y} is covered by a finite subfamily of the Oλ's.iii. Using ii, show that R is compact.Hint: In iii, it may help to look at, for each horizontal line, the union of the finite subcover. How "thick" or "thin" can this union be?Note: Using the same argument as that for ℝ, it follows from this problem that a subset of ℝ2 is compact if and only if it is closed and bounded.
