be blessed,nice and helpful video
Thank you so much for the encouraging words
Excellent video. It was a great introduction. I wish we had such clear explainations when I was back in school and college.
Thank you so much. That is so encouraging.
The 1st question is incorrect....
It's typing error. The point is. ( 0, -3,,-3). Sorry guys
Sorry it is a typing error. The point is (0, -3, -3).
great video
Nice explanation ma'am...❤
Thank you so much. Thats very encouraging.
great video
Very good Mam !! Excellent lecture 👍👍
Thanks ma'am 🙏🏼
Thank you so much
Thank you, Ma'am, for such an insightful video on harmonic progression. Your clear and simple explanations truly make learning enjoyable 😊. I got transported back to my first year when I was in your remedial maths class. I really miss the feeling of looking forward to your lectures every week. Also, I love that you highlighted the real-life application in music -- makes me look at the abstract concept with newfound interest. Thank you for making math fun again for me ❤
Thank you so much. Your kind words make me feel it was worth the effort to make the video.
thx mam it helped me a lot for my quiz
Thank you so much and glad it helped you. Best wishes for your tests.
Excellent Professor
Top !
Thank you so much
Outstanding academic class
Excellent
How to check solution like 2/17=1 6/23=1 Explain this madam
2/17 is the legendre symbol. For 2/17 use the formula 2/p= (-1)^(p^2-1)/8 . p is prime. So 2/17 = (-1)^36 =1 For 6/23 first write 6/23= (2/23)(3/23) for 2/23 use above formula 2/23= (-1)^(23^2-1)/8 = (-1)^66 =1 For 3 /23 use 3/p =1 if p ≡ ±1(mod12) otherwise = -1. As 23 ≡ -1(mod12) 3/23 =1 Please check my video czcams.com/video/ExPjXxf63yk/video.html on Legendre symbol for all formulas
please mention the mane of the theorem that you have used
I do not think the theorem has a name . It is proved using induction.
14:22 from where n1,n2 came😢
(I) m1=3, m2=5 these are modulus. M=m1 × m2 = 3×5 . Now n1= M/m1 and n2= M/m2 . I hope its clear
Very nice shared to others also
thank you for your great explanation ma'am. you really help me😊❤
9/13 =1 how? 2/17=1 Can sm1 say please
As (9/13) = 3^2/13 we used (a^2)/p =1 where p is prime. For 2/17 use the formula 2/p= (-1)^p^2-1 .So 2/17 = (-1)^36 =1
Madam (-1)^17^2-1= ? Please tell this madam
2/p= (-1)^(p^2-1)/8 . p is prime.
2/p= (-1)^(p^2-1)/8 .
great video
great video very well explained
❤
Than you
I'm very proud of you outstanding explanation
Thank you so much
very well explained
Thanks a lot for liking it.
Outstanding academic class
Thank you so much
🤩
Thank you for watching
Fine
Thank you for watching
Outstanding academic class
Thank you for watching
thanks a lot this was very clear and complete: nowhere else i've found tree methods for the resolution of a quadratic congruence!
Glad it helped! Thank you
Thank you 🌟
You’re welcome 😊
good video!
Thank you
Thank you, Professor. I have just discovered and subscribed to your channel. I hope that you are still making excellent videos like this one.
Thank you so much. Yes trying to.
Is there any method with O(1) complexity?
Try Hensel's Lemma
Can you explain the part where you introduce t, and how you go from 6(450) = 450-6t
Please check my video on solving diophantine euations in 2 variables. There I have explained how general solution is written in terms of a parameter t. Diophantine equations if solvable have infinite solutions and the different values of t give the infinite solutions
Thank you mam
Thank you for watching
thank you video i am not able to understand this in book as all question are given with using qdratic residue method which require more time ...ty
I hope it was useful
Nice class
Thank you
Nice
Thanks
Thanks for the video. I have two questions, if is possible: - how does it work the algorithm if a is even - how do you choose the y when solving xy = -b mod 2 ?
Not all quadratic congruence have a solution. For a even no solution will exist. You can check by giving different values to x the original congruence is never satisfied. put x=2 , 2^2-2 is not divisible by 2. 3^2 -2 is not sivisible by 2. ... As x is the initial solution, it is found from x^2 = a(mod2). Take an example if we are solving a congruence x^2 = 7(mod2), you can see x=3 satisfies . When we put x=3 in x^2 =a+ b2, gives 3^2 = 7 +b2 ,implies b=1 as x=3 and b=1 , xy= -b(mod2) is 3y=-1(mod2) solve this congruence. Here we can see y=1 satisfies so y=1
-3+164-7/14. = 11
yes thats correct should be 11. Typing error
Any job opportunity in Dubai mam? I have completed M.sc in Applied mathematics
Amazing mam 🌹❤️
thank you
I'm glad to found this video. Thank you very much
Glad it was helpful. Thank you.
how to eliminate y from the two equations?
Nevermind, I did it :D, make y=10-x and substitute in the first eq.
Need proof of the theorem
a|(bx +cy), therefore a|(bx +cy +fz +.....+nn) if it divides gcd. this is one of the first rule of divisibility, which is bezouts theorem
Very helpful! Thank you for sharing the step-by-step procedure in solving Diophantine Equation in Two Variables!
Thank you
Mam I have a problem that Prove that x^2 +y^2=z^2 With y even are x=r^2-s^2 , y=2rs , z=r^2+s^2 where r and see are arbitrary integers of opposite parity Can you prove it
Is this the way x^2 +y^2 = (r^2-s^2)^2 + (2rs)^2 = r^4 +s^4 -2r^2s^2 + 4r^2s^2 =r^4 +s^4 + 2r^2s^2 = (r^2+s^2)^2 =z^2
Very helpful. Great explanation!
Thank you
