Q. Exercise 1.1.2List all elements of the following sets:a. {n1∣n∈{3,4,5,6}}
Understand set notation: Understand the set notation.The set notation {n1∣n∈{3,4,5,6}} means we are looking for a set of elements that are in the form of n1, where n is an element of the set {3,4,5,6}.
List set elements: List the elements of the set 3,4,5,6.The elements of the set 3,4,5,6 are simply 3, 4, 5, and 6.
Apply formula to elements: Apply the given formula (1)/(n) to each element of the set {3,4,5,6}. We will calculate (1)/(n) for each value of n in the set {3,4,5,6}.
Calculate (1)/(3): Calculate (1)/(3).(1)/(3)=1/3
Calculate (1)/(4): Calculate (1)/(4).(1)/(4)=1/4
Calculate (1)/(5): Calculate (1)/(5).(1)/(5)=1/5
Calculate (1)/(6): Calculate (1)/(6).(1)/(6)=1/6
List all calculated elements: List all the elements obtained from the calculations.The elements obtained are 31, 41, 51, and 61.
