Most of the people does not notice this 3rd example of transitive relation (R-3) relation. Ye example tranisitive nahi hai kyuki
R3 relation mai (3,1) hai, (1,2) bhi hai, lekin (3,2) (R3) relation mai kahi bhi nahi hai
Hence it should not be transitive
Like if you agree 💯
yes
yes
Verg good
1,3 bhi nhi hai bro

Aa chuka hai
Sir inverse trigonometry ka ek video banado
Yess
Haa bro hmraye school exam me aarha h ITF
Q1)
F: N--N f(x)= x^2
One one, not onto
Q2)
F: Z--Z f(x)= x^2
Many one, not onto
Q3
F: N--N f(x)= x^3
One one, not onto( kisi ka cube 2 nahi dega)
Q4
F: R--R f(x)= x^3
One one, onto
Q5
R--R f(x) =[x]
Many one, not onto
Q6
R--R f(x)=|x|
Many one -1 or 1 = 1
Not onto
Q7
R--R f(x) =3-4x
One one, onto
Linear equations has infinite no of solution
Q8)
R---R f(x) = 1+x^2
Many one
Not onto

Bro for JEE you have to study many such topics which are deleted from NCERT like Periodic Functions, Odd- even functions, Transformations (Graphs), etc....

1:13:20 Equivalence class of (2,5) = {(1,4), (2,5), (3,6), (4,7), (5,8), (6,9)}
how can u explain
@@sasukegaming8289 The relation is a+d=b+c and here if u take (2,5) as a and b then we do need c,d such that d added to a and c added to be make them equal. Now 0 is not in the relation so cant be take and 1 added to 5 and corresponding 4 added to 2 make them 6 and 6 so 4 would be d since d is added to a. just like this (2,5), (3,6), (4,7), (5,8) and 6,9. You cant add 7 because then you would need then which is not in the relation
Sir.. PLEASE CONTINUITY AND DIFFRENTIABILITY ka ek one shot daal dijiye.. 😢kux smjjh nhi aa rhaa school mein..
1:13:32 equivalance class of (2,5) is
(4,1), (5,2), (6,3),(7,4),(8,5),(9,6)
Wrong answer hai. Elements ki position change hogi
Short and crisp lecture.Good for revising basics
Not good for studying for the first time?
1:13:50 sir equalence class of (2,5) is (1,4),(2,5),(3,6),(4,7),(5,8),(6,9)
Brother how?
(2,5)R(c,d)
=>2+d = 5+c
=>d-c=5-2=3
Therefore, we have to find those ordered pair whose difference is 3 from set (A×A)
@@bhaweshjha912 thanks buddy
@@animefusion-db8xv 😌✌🏻
1:52:11 but sir when we put (2,1) in the relation
then according to transitive definition that is if (a,b)€R , (b,c)€ R then (a,c)€R
here (1,2)€R ,(2,1)€R and as well (1,1)€ R. Which mean it is transitive n?
Exam se 1 din phele padhe wale 😅😂😂😂😂😂
Maths nhi 😂
Amazing video Jo doubt aaya wo agle question mein sir ne apne aap hi solve kar diya

How?
Sir inverse trigonometry kab aaya gai??
We need inverse trigonometric
Yes😊
I was literally waiting for lecture
and please month end tak inverse trigonometry ka bhi one shot upload kar dijiye ❤❤❤❤
Already uploaded plz check
bhai kab ke wa chuke
Sir transitive relation me last wala example transitive nahi hogaa... Kyunki usne (3,1) or (1,2) haai pr (3,2) nahi h.!
Sir any one of these is the main question
30:30 We have (3,1) and (1,2) but we don't have (3,2) so how can this be Transitive??
no but if u dont even have (1,2) in relation then it is transitive
@@NoobPro24boi I did not get your point
According to me it shouldn't be transitive
Yes @OpGamer-io3th I agree strongly with your point
Mai bhi wahi soch raha tha ki ye transitive kaise hua and sir ka ye mistake ko koi tackle kaise nahi kiya !
@@arabindamohapatra2550 According to me this is one of the biggest drawback of recorded lectures, teacher is also a human and he can also make mistakes. In live classes we can highlight the teacher's mistake but this is not possible in recorded lectures which creates confusion for us.
Continuity and differentiability
Answer of Homework question - Equivalence class of (2,5) is (1,4) (2,5) (3,6) (4,7) (5,8) (6,9)

Q1 ) F: N--N f(x)= x^2
One one, not onto
For every y belongs to N there don't exist and elements x in N such that f(x) = 2
F^n is not onto

37:29 (ii) is neither Reflexive nor Symmetric but it is Transitive
Thanku
39.14 question R (x,y):y is equal to x plus 5 ,x
Sir 30:33 me thoda wrong hogya aapse . I think ye transitive nhi hoga kyuki (3,1)∈ R3 and (1,2) ∈ R3 but (3,2) ∉ R3
