Write a function in python that takes a set A and a relation R(x, y) on A (as a python function such that R(x, y) returns true if and only if the relation xRy holds), and returns True if and only if the relation R is reflexive. Here is the function signature you need to use.
ANSWER:-
CODE:-
def y(x, y):
return x == y
def n(x, y):
return x == y and x != 3
def is_reflexive(A, R):
setA = []
for i in A:
setA.append(i)
s = []
for i in setA:
for j in setA:
if R(i,j):
s.append((i,j))
for item in s:
if item[0] ==
item[1]:
setA.remove(item[0])
if len(setA) == 0:
return True
return False
s = {1,2,3}
is_reflexive(s,y)
is_reflexive(s,n)

8. On the set A = {1,2,3,4,...,20}, an equivalence relation R is defined as follows: For all x, y € A, xRy 4(x - y). For each of the following, circle TRUE or FALSE. [4 points) a. TRUE or FALSE: There are only 4 distinct equivalence classes for this relation. b. TRUE or FALSE: If you remove all the even numbers from A, the relation would still be an equivalence relation. C. TRUE or FALSE: In this equivalence relation, 2R5...
Let R be the relation on N defined by xRy iff 2 divides x+y. R is an equivalence relation. You do not have to prove that R is an equivalence relation. True or False: 3 ∈ 4/R.
Jupyter code (PYTHON) True error Write a function called trueError that takes the following inputs: • X, the new value • Xtrue, the previous value And returns the following output: • error, the calculated relative error The formula for the relative error is shown below: errue = 11100% In (): def trueError(x,xtrue): # YOUR CODE HERE raise Not ImplementedError() In (): # You can call and test your function here # YOUR CODE HERE raise Not ImplementedError()
QUESTION 30 Let R be the relation on the set A={1,2,3,4,5} given by R={(x,y): y=x+2}. What is the size of RoR? QUESTION 31 How many relations on the set {4,5} are reflexive? QUESTION 32 How many relations on the set {4,5} are not reflexive?
def max_of_two( x, y): ifx>y: return x returny a. Write a Python function called max_of_three( x, y, z ) to return the largest numbers of three numbers passing to the function You can use the function max_of_two in your solution. /Your code

IN PYTHON: Write a function that takes, as an argument, a positive integer n, and returns a LIST consisting of all of the digits of n (as integers) in the same order. Name this function intToList(n). For example, intToList(123) should return the list [1,2,3].
Let the relation R be defined on the set {x ∈ R | 0 ≤ x ≤ 1} by xRy ⇔ ∃t(x + t = y and 0 ≤ t ≤ 1) Is R transitive?
4. Consider the relation on the positive integers xRy if and only if x x+y (a) List three ordered pairs from this relationship (b) Is R reflexive? Prove your answer (c) Is R symmetric? Prove your answer (d) Is R anti-symmetric? Prove your answer (e) Is R transitive? Prove your answer.
python Write a function that takes as input a single integer parametern and computes the nth Fibonacci Sequence number The Fibonacci sequence first two terms are 1 and 1(so, if n - 2 your function should return 1). From there, the previous two values are summed to come up with the next result in the sequence 1.1,2,3,5,8,13, 21, 34, 55, etc.) For example, if the input is 7 then your function should return 13 26561.1615880 1 def Fibonacci(n): # your...
