THANK YOU SO MUCH!!!! U r the best SAT content maker in the RUclips industry!!!❤❤❤❤❤❤
plz replace my linear teacher 🙏🙏🙏
i luv u
Bro as a jee aspirant it is nothing
You can’t compare the sat to the Jee the sat is a lot faster paced test and also has an English section that test your vocabulary knowledge of a couple 1000 words that aren’t like common sense words. And sat is for general admission even stuff like art schools not strictly for getting into prestigious engineering or math related programs. Even with a perfect sat your not garenteed a spot at selective schools.
Then, Why are you here for? Go and do your JEE shit . Giving SAT is far better than giving yourself a mental torture or studying like a slave for JEE . USA is far better option than staying in India after JEE clear.
Q2 put in desmos u get answer -13
Nice video ❤
was waiting for this video. Waiting for more
saved me ong exam in 4 days
thank you
This is a good video though I got confused probably since this is a video for those already familiar and going through it quickly while I knew nothing
I did all ur questions on a pice of paper
Me too
great explanation thanks!
These questions are in the book I have
damm really gotta be creaetive with these
Where did you disappear bro
More vids soon
Best teacher
Mountain Drew 👏
the absolute goat tysm
you deserve more likes and subscriptions tbh U do a great job I am sharing it with all of my friends!
Thank you so much 😀 Good luck with your studies!
Thank you x10000!!
needed this, thanks for creating this. :)
you're goated
plz turn your camera off in future videos. I'm trying to really focus so i can get a high sat score but your pretty face keeps distracting me
amazing video. waiting for more of these
Currently a student taking Linear Algebra, appreciate these videos! They're a big help when the professor just repeats the textbook verbatim in the lectures.
9:47 Can I consider x^2-5k-10 as a qudratic function and find its roots instead of equating x^2 to zero? I've done it this way but cannot get the correct answer for some reason, is there any explanation why my method does not work? Thank you for a great video!
no, for x^2 -5k -10 to be considered a quadratic function 5k should act as a coefficient to x. it would have to be x^2 - 5kx -10. think of (-5k -10) as c in the standard quadratic equation, as it has no variable and, therefore, is a constant.
Learned something new today , thanks
VERY MUCH DIPHICULT BIRO 🤣🤣🤣🤣
Is not the fifth question‘s answer 5/9?😶🌫You know 54(x^2+5/9)(x^2+7/2)
Hello Drew, thans for the awesome work. I have a question. If we prove that those vectors span the whole R3, then isn't it obvious that they also have to be independent, considering the fact that if at least one mas not linearly depended on the others, then the space produced from the linear combinations would be just a plane of the whole space? I have seen again this kind of proof and I am a little bit confused. Thank you in advance!
Great question. Fair warning: my background is engineering, not math, so people studying pure math can feel free to chip in here. How would you prove those vectors span R3? I see your logic, but I’m not sure it’s rigorous enough to just claim “since the vectors span the entire vector space, they must also be linearly independent” for our proof. I seem to remember this explanation not being sufficient during tn studies. I would suggest looking into the theorem where this logic comes from to explore this further
6:39 linearccombi gives vectors
Thank you, sir. I could not even find this in my textbook.
for question two if you want to do less math you could just plug in the x and solve for the y, and if it matches up with the y in the solution you would have found your answer
Very helpful, thanks! Amazing job.
is there any ways to solve these using desmos?
yes, most of these can be made a lot easier with desmos
You kinda look like Farkle lowkey… (compliment) blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhWMPPcUCH9Vlynz5WY-cbFIH6QUbhyphenhyphenEbSkBuJVJFuN8nAuYh3X-hqnLDIrKa9PcOGdlKBXlJ5giWQ8a_s2zTfywrfn29p1ejM-VBvEZnHj6ZyFajdymdaoR8bWMNdrIHBEd-1jVSwGkpE/s1600/farkle2.jpg
19:38 but this is only possible when the expression is equal to zero, which is not given...? How does hippy do that?
LOVE YOU SO MUCH
kabhi JEE DEKE DEKHO ji
Thank you so much, had me stumped since we are doing complex no.s for the first time.
I dont understand the first question solution. If we are comparing values of x and J, then why when x is negative and J is positive, why are saying that x>J?
Hey do you know which subreddit this question is from or do you know any subreddits that post harder questions? Thanks!
3rd question was the hardest on here imo
but the question is asking for a column space of a polynomial. There isn't even a matrix given in the question.
The first question’s answer should be only II, not neither I or II
good job boyy❤🎉
Thank you!
please show us how to do question 1 and 2 this with desmos cuz using this methode take too much time
For the k problem at 6:37 the solutions are -11/5 from the first factor, -sqrt(5k+10) from the second, and sqrt(5k+10) from the third. Then just use desmos regression to solve for k: (-11/5) * (-sqrt(5k+10)) * (sqrt(5k+10)) ~ 154 PARAMETERS k=12 Done
I didn’t get your point can you please explain it a bit more
could you make an in depht video on when we can apply regression?
@@user-vk3od9cp6n Rather than solving the equation by hand, you can use Desmos to solve the equation for you, i.e. once you get to the step where you have the product of the roots equal to 154, (-11/5)*(-sqrt(5k+10)(sqrt(5k+10) = 154, you can solve that in Desmos using regression. Or you can just type the equation (replace k with x) and then look for the vertical line at x= 12.
I did not get this: at 6:52, how can taking a derivative helps us find the roots of vertex?
The roots of f’(x) tell us when f(x) is at a minimum, maximum, or inflection point. This is because the slope of the tangent will be 0 at that point. Since g(x) is a quadratic, we know the roots of its derivative will tell us when it reaches its vertex.
Great! Thanks for this simple and intelligent explanation!
