Please Answer Exercise 2. Advanced Thankyouu?❤ Definition. A metric space (X, e) is a set X with a distance function or metric p satisfying the followingnmnertieeProperty(4) is called the triangle inequality.Example.1.Let X = R and p(x, y) = |x – yl, the usual absolute value in R. It is easy to verify that (R. p) is a metricspace. The defined p satisfies all the properties.(a) Since the absolute value only gives value of nonnegative real numbers, then it is guaranteed thatfor all x, y eR, we have 0s |x –- yl. Thus, 0s p(x,y).(b) Note that p(x,y) = |x – yl = 0 if and only if x - y = 0 and that is if and only if x = y.(c) For all x, y ER,P(x, y) = |x – yl = l(-1)(y – x)| = |(-1)lly – x| = ly – x| = p(y, x).(d) Recall that the triangle inequality for real numbers states that if a, bER, then la + b| < Ja| + |bl.For all real numbers x, y, z, we have,Study Guide in_ Real AnalysisFM-AA-CIA-15 Rev. 0 03-June-2020Math Elective 2 (Real Analysis)Module 2: Abstract Integration|x - yl = |(x – 2) + (z – y)| s lx – z| + |z –- yl.Thus, p(x, y) < p(x, z) + p(z. y).This is the Euclidean metric on R.2. Consider X to be a non-empty set and definep(x. y) = {6 fx =yWe check if the conditions for p to be a metric are satisfied.(a) Since the possible values of p are only 0 and 1, thus, 0s p(x, y).(b) The definition of p gives us that p(x, y) = 0 if and only if x = y.(c) Note that if x * y then y + x and similarly, if x = y then y = x. Thus, p(x, y) = p(y,x).(d) To prove triangle inequality for p, we have to considerthe cases of equality of any realnumbers x, y. z.(i)Let x = y = z. Then, p(x, y) = p(x, z) = p(z, y) = 0. Thus, the inequalityp(x, y) S p(x,z) + p(z, y) (i)Let x = y = z. Then, p(x, y) = p(x, z) = p(z, y) = 0. Thus, the inequalityp(x, y) < p(x, z) + p(z. y)holds.(ii)Let x * y + z. Then, p(x,y) = p(x, z) = p(z,y) = 1 andp(x, z) + p(z. y) = 1 +1 = 2.Thus, p(x,y) s p(x, z) + p(z, y).(ii)Let x + y and y = z. Then, p(x, y) = p(x, z) = 1, p(z, y) = 0, andp(x, z) + p(z, y) = 1+ 0 = 1.Thus, p(x, y) s p(x, z) + p(z, y).(iv)Let x = y and y # z. Then, p(x, y) = 0, p(x,z) = p(z, y) = 1 andp(x, z) + p(z, y) = 1 +1 = 2.PANGASINAN STATE UNIVERSITY3Study Guide inReal AnalysisFM-AA-CIA-15 Rev. 0 03-June-2020Math Elective 2 (Real Analysis)Module 2: Abstract IntegrationThus, p(x, y) s p(x, z) + p(z, y).Hence, (X, p) is a metric space.Exercise 2.
