Mam plz trick video ka playlist de dijiye

[P_sharma]

33:46 yes its reflexive transitive and symmetric

[Zubair-sx]

33:42 yes mam it is transitive as we have (a, b) and there is no (b, _) so we say it is transitive

[simransheetu]

Thankyou so much mam for providing all the concepts your teaching way is very good

Ans of Que 6.
you say this:- Let the relation R in the set A = {x EZ: 0 ≤ x ≤ 12}, given by R = {(a, b):la - bl is a multiple of 4}. Then [2], the equivalence class containing 2, is:
The relation R is defined as R = {(a, b): |a - b| is a multiple of 4}, and the set A is given as A = {x ∈ Z: 0 ≤ x ≤ 12}.

To find the equivalence class [2], we need to determine all the elements x in A such that (2, x) ∈ R. In other words, we need to find all x in A such that |2 - x| is a multiple of 4.

Let's calculate the differences between 2 and the elements in A and check if they are multiples of 4:

|2 - 0| = 2, which is not a multiple of 4.
|2 - 1| = 1, which is not a multiple of 4.
|2 - 2| = 0, which is a multiple of 4.
|2 - 3| = 1, which is not a multiple of 4.
|2 - 4| = 2, which is not a multiple of 4.
|2 - 5| = 3, which is not a multiple of 4.
|2 - 6| = 4, which is a multiple of 4.
|2 - 7| = 5, which is not a multiple of 4.
|2 - 8| = 6, which is a multiple of 4.
|2 - 9| = 7, which is not a multiple of 4.
|2 - 10| = 8, which is a multiple of 4.
|2 - 11| = 9, which is not a multiple of 4.
|2 - 12| = 10, which is not a multiple of 4.

Based on the calculations, the elements in A that are related to 2 under the relation R are 2, 6, 8, and 10. Therefore, the equivalence class [2] is {2, 6, 8, 10}.

Mam question number 4 kya aap thoda explain kar skti hai pleasse

[suvivlogentertainment]

Mam..10 number ka answer none of these kyu nehi hoga or transitive kyu hoga isse me kya logic he...
