I m in first year college now ...just came here to thank you ma'am....your videos have always been helpful for me in both 11 th and 12 th ....i passed my 11 th exams just by watching your videos...Thank you for everything ma'am....You deserve the best!!!
Ma'am I didn't understand one thing. On 1:19:01 we have taken these two matrices. Since we are only given the data and we make matrix B as A and A as B, then our answer completely changes, i.e as it's in m*n (1*3) order and n*p (3*1) order resulting into m*p order of C (1*1) and now with opposite row and coloum it will be the opposite resulting into C (3*3). I hope you got my question. How will we understand when do we have to take out 3*3 and when 1*1 here because if the Matrices are changed the order completely changes.
Whenever we are multiplying any two matrices, example : a x b and b x c. there is one mandatory condition that we have to follow be have to see that if b=b, as in given example the condition is satisfied. a x c will be the order of the product of two matrices. Example: If order of A matrix is 4 x 2 and B matrix is 2 x 6. Here the condition is satisfied 2=2 and the order of the product is 4 x 6. If condition is not satisfied the product of the Matrices does not exist.
@@saeemuthe2387 in that given question, ma'am has taken 1*3 as the order of first matrix and 3*1 as the second right! If we are taking first matrix ie, about the books as 3*1 and price matrix as 1*3 then also this condition is satisfied..no.. I'm bit confused! Can you answer this one also..
When ever I search for any chapter a list of 10 to 15 videos come . 😣😣 This is only channel who complete the whole chapter in one video 😍😊 Thank you so much
YOUR ONE-SHOT VIDEOS ARE REALLY A BLESSING. How easily and simply you can explain the whole chapter amuses me every time. Concept hua bilkul crystal clear.
1:02:49 Agar koi matrix A ( 2×4) order ki h aur koi dusri matrix B ( 4×3 ) order ki h toh AB = Matrix ( 2× 3) order ki hogi pr ye toh possible hi nhi h. Agar first matrix k column = second matrix ki row Then must check First matrix ki row = second matrix k coulmn k

Thank you ma'am it is really a good introduction of matrices how easily u explained it. I wanna ask u that how r u intelligent in every sub. I know it is a strange question but I'm curious to know
Ma'am idk whether u will see my comment or not but in the inverse matrix sum, u should have written apply 1/5R2 rather than 1/5R1 cuz even if we do it that way the sum will change a Lil bit atlast .... 🙏
I stumbled upon this video after many months and just came here to show my gratitude to you ma'am . I did not join any coaching in 11th and 12th sci . I was very afraid that , i will not pass without coaching . But your videos have saved my life ❤ The only reason i passed my 12th grade was because of your videos . I give a big credit of my success to you .I still can not believe that this much incredible content is free of cost and available for everyone . Your favourite lines are incraved in my head for forever like " hello and welcome to learnohub " or those memorable lines of " Crystal clear " 💙 Your channel will be very nostalgic and memorable for me . Thankyou so much for all your hardwork in providing quality education with very easy techniques and understandable visualisations . 😊 May you keep educating more and more childrens like this .
finally we the students of class 12th are here to study the first chapter in a 1 shot video when only some days are left for the exam ....we are the only legends of India and we are watching this video,, but the real thing is that we don't even know the basics of the chapter and we haven't done our 11th sincerely ............hope we all do good in our exams ...and we are still promising our self that we will study hard in the 2term ...but myself know that ...the same situation is going to be reaped in the march itself......... ALLL THE BEST TO EVERYONE HERE 😐 HOPE YOU ALL PERFORM WELL IN YOUR EXAMS 😅
Whether it's my exams or just a normal day for me to learn new concept or it's my neet preparation time, u have always been such a great source of reliability for me for all this. I am old follower and is so happy to see you everytime coming back with same energy and enthusiasm for the kids u don't even know. Cant express the gratitude and huge amount of respect I have for u with words. Thankyou! ❤️
Time starts -- 48 Problem 1 It proves associative property A +( B - C) = (A +B) -C =(A - C) + B This may be proved according to associative property Once again we may prove A +(B - C) =(B - C) + A in accordance with commutative property.

Mam, Their are no videos on 12th more chapters of you. I want your more teaching videos on crash course 12th maths. I seen full 11th course. I like most it than other RU-vid videos. Plz make more videos on 12th maths crash course video, that you not teach till.

Ma'am ,I have a doubt regarding question [q.1 ] -find the values of x y z from the following i.e x+y z ,5+z = second matrix i.e 6 2,5 8 ...but what if the order of the matrices is different then how to find the values?
Your way of explanation is brilliant mam..... I just loved the way you clear the doubts..... Thank you so much .. The videos are so helpful.... You are blessed with such a gift of teaching .... Your teaching skills are really praiseworthy .❤✨😍✨❤❤❤❤❤❤
1:17 if you multiply row matrix with columns matrix then you will get 3*3 matrix, but if you multiply column matrix with row matrix you will gat 1*1 matrix and this 1*1 matrix is equal to the sum elements of main diagonal of initial 3*3 matrix.
Awesome, amazing, bhannat ,wonderful ,supereasy explaination mam . Before u i tried to learn this chapter from my elder sis and 2 more popular channels but they made it super boring and it seemed to me that this is going to be more difficult than determinants but ur explanation is forcing me to attempt the questions right now ,thanku very much
@@sumedhvats1395 yup, im in 12th now. picchle do saal ive spent time doing math instead of focusing on neet and now theyre telling me to score good marks in boards and neet :/
mam,i have a question.in the last part of the video,,inverse of a matrix using elementary transformation....how we will understand how to transform? can you make me understand please???
Ma'am thank you for the video. But you have not covered these following topics: 1. Rank of Matrix. 2. Co-factors of matrix. 3. Transpose of Co-factors of Matrix (adj. A) 4. Matrix Method of Solution of a System of Linear Equations. 5. Application of Matrices- Leontief's Input-Output Model
is zero matrix a diagonal matrix? or if one of the element of main diagonal is zero for a 3x3 matrix then is it a diagonal matrix? for example- | 3 0 0 | | 0 0 0 | | 0 0 2 | & [0]
Ncert syllabus changes in decades.... so all the topics covered here are exact same at least for this year also..... and i predict that it might be same and significant for upcoming years also
Hi mam, ur really great.....🙏🙏 You are the one who inspired a lot to me mam. If you don't mind can you please explain in English mam it's helpful a lot for all the student because English is easy to understand and more comfortable than hindi.......☺️
@@LearnoHubClass1112 can you please please please cover entire class 12 syllabus like this.... i mean each lesson in one shot video... please please please please,,,,, you teach so well even without pen,pencil,board,chalk,dustr..... thank you so much
Grt work ur doing mam 👍 apko Salam and it will be better' if u add this hindi videos to your app we can access your video easily or else you can make separate video playlist in Hindi your channel.
