For those who forgot Cartesian product The Cartesian product is a mathematical operation that combines elements from two sets to create a new set. It is represented by the symbol "×". To find the Cartesian product of two sets, you pair each element from the first set with every element from the second set. The result is a set of all possible ordered pairs. For example, let's say we have two sets: A = {1, 2} and B = {a, b}. The Cartesian product of A and B is: A × B = {(1, a), (1, b), (2, a), (2, b)} Each ordered pair represents a combination of an element from set A with an element from set B. The Cartesian product allows us to explore all possible combinations between two sets. 😊

Surjective (onto) proof is wrong at 56:25. The presenter actually makes a wrong calculation. This is how I would prove it... f(x)=2x means y=2x. As x belongs to N, y can only be an even natural number (as it is multiple of 2). But y also belongs to N. So, all values of y that are odd natural numbers do not have a corresponding x (that is, 3/2 is not a natural number and cannot be x). Hence f(x)=2x is not surjective. Hope this helps.

Such a huge inspiration you are ma'am.. From the core of my heart thank you very much for taking your time for us and teaching us so effortlessly and for clearing our doubts ❤
Pura chapter samaj ma aa gaya tha es video ka baad?
Thank you ma'am, you cleared my doubts, will surely score full in R&F portion :)
Mast jhoot bolte ho.....🤣🤣 Man ne ko padega..... tumhe.....👌🤣
Surjective (onto) proof is wrong at 56:25. The presenter actually makes a wrong calculation. This is how I would prove it... f(x)=2x means y=2x. As x belongs to N, y can only be an even natural number (as it is multiple of 2). But y also belongs to N. So, all values of y that are odd natural numbers do not have a corresponding x (that is, 3/2 is not a natural number and cannot be x). Hence f(x)=2x is not surjective. Hope this helps.
Here before 3-4 months before boards 23-24❤
Finally it's November and I realised I should study now but still wasting my time writing a comment.🙂
U are not alone brother

Mam,I am really very excited to feel your teaching formula, but in current situation,I need chapter 5 ,
for reflexive relations if we take set of whole no.s then the condition (a,a) belongs to R holds true for a=0 & b = 1
For Boards 2022-23, Watch till 1:03:10 .....
Hope it helps.....
Thankuuuuuuuuu♥️♥️♥️
Ma'am please start a series completely dedicated to class 12th boards including boards PYQ solving, expected questions, A-R type questions, correct way of writing and presenting answers in board exams etc ...Please ma'am!!
Some of us got this channel at the end of class 11 when we haven't done a single online classes and before exam we went to this channel to get some 💡idea 😁😁😁

If you are watching this video when it's your maths board exam day after tomorrow then congrats legend
Composition of functions is a critical and difficult part of this chapter.
Think backwards logically and u will understand its details , genrally compostion means adding one function into another's
Damn just realized i started studying a little too late.....but feeling relieved since i know i will complete my course and catch up to others in time since ma'am teaches so well that you understand the concepts really easily...although i will have to work hard to do the exercises and do many question solving from books :_)
Same 😀😀

Mam your way of teaching so good 👍.
I always learn your way. 😊😊😊
Let E subset R and f, g, h are the functions from E into R. Suppose a £ E and f, g, h are continuous at 'a', then for h(a) #0 the quotient f/h is surely
(A) bijection
(B) not continuous at a
(C) surjection
(D) continuous at a
Mam you teaching style is marvelous...I am your old student mam learning from you ,after watching your videos it gives me happiness and confidence...Thank you for all you give us.🙏🙏🙏
58:31, shouldn't this be NOT INJECTIVE. If x1^2 = x2^2, then x1 can be equal to either x2 or -x2. Therefore it can be 2 values and is many-one.
