A1 Rewrite the following sentence using variables and logical or mathematical symbols. Limit yourself to as few English words as possible, but it must be an equivalent statement. "e to the power of some integer times the square root of minus 1 is a complex number that is not real”. A2 Let S := {kt, ..., kg;} be a set of containing certain possibly equal complex numbers, and let T be the set of integers lying...
Let U be the set of all integers. Consider the following sets: S is the set of all even integers; T is the set of integers obtained by tripling any one integer and adding 1; V is the set of integers that are multiples of 2 and 3. a) Use set builder notation to describe S, T and V symbolically. b) Compute s n T, s n V and T V. Describe these sets using set builder notation
Please explain as detailed as possible, thank you!
1. Let S={0, 1, 2, 3, . . . , 150). and let A={x E S | x+100 E S} Write the roster notation of the set A. Also, find the cardinality of the set A. 2. For each natural number n, let An be the interval An (0,2/n) and let Bn be the interval Determine the following: (b) Un1Bn 3. Let the universal set be S = {1, 2, 3, 4,...
7. There are 52 playing cards; let S be the set of all of them. A "deck" is a particular order (or permutation) of the 52 cards. Mathematically, a deck can be represented by (ci,, 2) where ci,c2,., cs2 are all the elements of S. The interpretation is that ci is the first card in the deck, c2 is the second card, and so on. Let 2 be the set of all possible decks. a) Is Ω a subset of...
Let n > 1, and let S = {1, 2, 3}" (the cartesian product of {1,2,3} n times). (a) What is Sl? Give a brief explanation. (b) For 0 <k <n, let T be the set of all elements of S with exactly k occurrences of 3's. Determine |Tx I, and prove it using a bijection. In your solution, you need to define a set Ax that involves subsets and/or cartesian products with known cardinalities. Then clearly define your bijection...
