Albert Einstein said that quote at the end jackass, it's not anonymous
There’s a problem thought this only works if the events keep changing if you keep the 1m changes from door to door in each experiment otherwise the probability of winning is much less than 66% this is something most people don’t say
6:24 Looking for confirmation; should the formula for e_i have y_i instead of y_1?
I do enjoy these equations, yet I find it difficult to remember all of the steps to the process. It's not that it's difficult to understand, but mostly just too intricate to remember all of the procedure and formulas after a prolonged duration. I feel like this is one of those math concepts I'll learn for a test, then immediately forget afterwards.
haters will say the function is not defined piecewise

Bought sour cream, opened it & found it literally half full
@@grandebigy Let me guess, the container was the same size.
@@Mathispower4u same size as previously full
Big thanks from ALGERIA. you have a good pedagogy for explaining your lesson.
Thank you for your comment!
This concept took forever to wrap my head around but the video finally got me to understand it thank you 🙏🙏
Slow Down!
❤❤❤❤❤
TWIST ON TWIST THE ANSWER IS NO
Consider me hooked! Looking forward to more from your channel. 💞
Thank you. I appreciate your support!
Thank you for helping

Fantastic! Thanks
I am having trouble finding your video where you show how to do a double integral with ()^# with bounds of 1 and 0 Do you have the name to that video by chance?
Very interesting
Pretty tricky. How fair is this, though?
What about col 2 had 3 zeros and a 1
for your second example, (-4)(-2) you can just use 8 zeros instead of 12 since you only be removing 4 sets of 2's ...
oh yeah 6 hours on calc so far
I absolutely love how you keep the steps on the same slide. It's effective and I can reference the problem back. It's easy to follow and easy on the eyes. I love your videos so much.
You, alone, have helped me for 2 years now. You are beyond amazing.
Thank you! I appreciate your comment and am glad I could help. 😁
Thanks man, I was really confused on how to find " a " !
Noice
I need help doing the bigger problems like how do u borrow?
COOL! 😊
Watching in 2024 .... Thanks alot for making this bearable😂
what is a conjugate I dont get how he just put 1-cos/1-cos in minute 3:20
thank you i just cant seem to comprehend this stuff unless i see the problem being done , your a life saver
I am glad I could help!
ur voice fucking sucks and u breaTHE WEIRD
thanks bro
I'm solving exact same type of question buts like like the double derivative of same one but instead of getting cf''(x) key says answer is (c)
This was so helpful!! Thank you!!
super helpfull
Thanks so much for the instructions. Now I will go beat the exam😎😎
this feels really out of the spirit of the actual problem, I think what they want you to do is first recognize that x is composed of both of A's eigenvectors which are written inside of the P matrix. After seeing this we distribute the A matrix across both parts of x. We know that when you multiply a matrix by its eigenvector, you receive that eigenvector times its eigenvalue. We know the eigenvalues as they are written in the diagonal entries of the D matrix so we multiply the eigenvector by the eigenvalue and then again by the coefficient in front. for example when multiplying A by 4 * (3 , 1), we know that the eigenvalue for (3 , -1) is -4 so we get that A * 4 * (3 , -1) = 4 * -4 * (3 , -1) = (-48,16) then for the second part when multiplying by 8 * (1 , 0) we know that the eigenvalue for (1 , 0) is 2 so we get that A * 8 * (1 , 0 ) = 8 * 2 * (1,0) = (16,0) then just add these vectors and you get the answer (-32, 16) When the problem says do not compute A, it implies don't just shove all the vectors in a line and multiply them... it feels strange to me to try to weasel out of it by multiply right to left and pretend like you didn't basically do the exact same thing... You didn't use anything about the properties of P or D and did nothing about the matrix being actually diagonalizable.
Yes, I don't know why I didn't notice the eigenvectors as parat of vector x as well as the columns of P. Thanks for the comment. New version: ruclips.net/video/O3F5vfU6Icw/видео.html
@@Mathispower4u awesome, apologies if I came off irritated-I was deep in a linear algebra haze 🤣
I still don’t get it :/
Please help, i cant find one show, where they vote for the right answer, the question was the same
i've been working in the real world for 17 years and i have never once seen this be applied to anything i've done or been around. old people making up stuff and putting numbers in random places calling it math. Nothing elementary about these matrices. But finish strong people. All this for a piece of paper that says you can start something and finish it. Employers love this.
I fuck w the ending quotes heavy
the GOAT
huh?
Thankyou very much sir!!
the quote was by zig ziglar thank you for the video
Thank you very much!
for those who were completely lost at f(x) = -9 like i was, someone in the comments helped out: you plug x = 2 into the function f(x)=ax^2+bx+c, in this case you'll substitute x for the number 2 in x^2 - 4x - 5 so (2)^2 - 4(2) - 5 = -9
Thank you so much!
Between my professor and these videos. Differential equations is becoming really easy. Painful to stay organized, but this is algebra. It is fun.
