Just came across your video, this is the first math video i've found on youtube that really helped me understand what I was learning! You are a great teacher thank you so much for your help and enthusiasm :)
If you had to calculate 2^100 and 3^100 without a calculator, you would probably do exponentiation by squaring. That takes advantage of this exponentiation property: (a^b)^c = a^(bc). So by repeated squaring of your last result, you can compute 2^2 then 2^4 then 2^8 then 2^16 then 2^32 then 2^64. Once you have those, then you can do this operation to get 2^100: 2^64*2^32*2^4. That means that you can calculate 2^100 by multiplying 8 times! The first multiplication would be 2*2=2^2. The second would be 2^2*2^2 = 2^4. The third would be 2^4*2^4=2^8. The fourth would be 2^8*2^8=2^16. The fifth would be 2^16*2^16 = 2^32. The sixth would be 2^32*2^32=2^64. The seventh would be 2^64*2^32=2^96. The eighth and final would be 2^96*2^4=2^100.
This channel is a gem! Great video quality, great lecture, great teacher with a great sense of fashion! One question though, shouldn't the inverse of the matrix be (1/det)[ d -b over -c a]?
To raise anything to the 100th power, we multiply it by itself not 100 times, but 99 times. To square it, we multiply it by itself once. To cube it, we multiply it by itself twice... etc.
Got this video in recommendation had a playback of first 30 seconds without clicking the video the great introduction made me open this in my other tab. Now I'm going To stalk your whole channel for Linear Algebra content 🤣
So for any nxn matrix there are n! sets, of numbers, of cardinality n^2, that lead to its diagonalisation. I didn't know that before :-) (just messing ... good video)
I was taught that for these kind of questions First do A², ³, ⁴... until you see a pattern in these Analyse that pattern and then put for the exponent asked And it works, atleast the questions I solved were right

when I think of maths, I think of a gentle man like him teaching. you really are the best
"Do not confuse yourself"
Great advice! 🙂👍
rapidly becoming one of my favorites chanels on youtube, thanks a lot for the great videos.
ive never watched such a relaxing math tutorial
Glad you liked it!
thank you for actually explaining every step, unlike my teachers
you are the mentor figure every aspiring young man need in their life. Love your enthusiasm and energy !

I went from failing linear algebra to getting 80s on my exams thanks to your videos... Thank you so much

Thanks
you actually make me smile even though linear algebra is my least favorite course. thank you a lot
This guy needs more popularity truly underrated
i watced all videos in the palylist , have learned too much. Thanks
Glad to hear that
Most informative RUclips video ever!

Didn't know kamaru usman was that good at matrices
I was thinking that I saw him somewhere else too

This was SO SO helpful. Thank you!!!!
You are really best man
What a king
Than you so much
Thank You

Smart!
@@PrimeNewtons yes Imagine without knowing this the question comes for a 3x3 Matrix to the power of 2023 (that was one question a remember)
I am now happy!
@ 0:07 Great bit of theatre! LOL
never stop learning cze when you stop learning stop living clear mssg'''
thankyou sir
ty very much man!
Just to make sure, you did the inverse P wrong or not because you didn’t take into consideration the sign of the cofactors
Correct
smile😁

2^100 be casually having 30 digits lol
