Determinant of a 2 x 2 Matrix - A Few Basic Questions

[@Masn7o2]

just want to say patrick that your videos have helped me get through highschool i dont know hwat i would have done without your videos..... thank you keep up the good work man

[@vusiliyK]

Im more than half way through this semester in linear algebra, and thanks to you and the book, I'm doing well even though i only came to class on the first day.

[@MrSingh1430]

You sir, are the best teacher. You help me pass a failing class with flying colors. Thank you sooooo much

[@redsader86]

I teach Math at a small Christian school and this helps alot! Keep them coming!

[@TheKaveshan]

Who needs lecturers when youve got Patrick.U ROOCCCCKKKKK

[@SharpShocks]

You are helping me prepare for an upcoming test. Thank you for this.

[@maggiebarnes4905]

you are a math angel

[@Vorbis5]

Your videos are infinitely good.

[@Freelancerk1bbles]

What is a determinant? Do you have a video explaining this? I guess I'll go google it and try to find out.

[@michaellopez6095]

its a special value that you get from a matrix that can help you find the inverse of a matrix...

[@kamalraj2978]

Thank you buddy😁 This helped me a lot!

[@Misacura]

i probably have one of the worst math teachers ever so bro thank you for your vids cause i can come home and learn the lesson and turn in my home work and actually understand and know what the hell im doing

[@XXInuyasha99XX]

Thank you so much! I really love your handwriting!

[@marinasidabutar505]

THANKS

[@patrickjmt]

perfect, come back any time :)

[@joshuapereira918]

this is fire :) thank you boss

[@ryanjoyce1876]

Hey patrickJMT! I have a few questions regarding matrices, what aspect of a coefficient matrix would indicate that there is not a unique solution? And with working with simultaneous equations in the terms of two lines what does inconsistent and dependent mean? Thanks :)

[@patrickjmt]

@Darathexplicit i was not at all offended in the least ; )

[@vishalKaradeprofile]

simple, nice work.

[@esraalafta202]

thank you soo much ,you really a good teacher ,have a good day :)

[@patrickjmt]

come back any time :)

[@zenyeo2376]

Thanks! Wasn't taught b4.

[@JC_Widmer216]

sorry Patrick, I just wanted to let you know that at 0:59, that 4 is not negative but it is positive

[@craigvyfers595]

Awesome Pat!!!

[@electricalengineeringlectu647]

sir how we can calculate determinant of matrix 12 power

[@latika1998]

Thank you so much!

[@SkinDeepBeauty12]

thanks for the help!

[@Onisha141]

You are the best!

[@marielalfonso5083]

Thank you!

[@patrickjmt]

@Darathexplicit hahhaa sweet!

[@berthazulu7318]

Wow m greatful to u sir

[@Boutiki]

Wait a minute when he got 40 + 40 aren't u suppose to to subtract ???? Why did he add and got 80 yeah i know 40 + 40 = 80 but ???? Idk

[@vinnv226]

He is subtracting away a negative 40 (4 times -10 is -40) which is equivalent to adding 40.

[@Boutiki]

Thanks i got it

[@yusraahotee6879]

thx a lot!!!

[@Coreanologo]

THANK YOU FOR EXIST :D

[@kaiche4939]

I love you.

[@ericluo4900]

teach in my school =(

[@michaellopez6095]

I don't get it! *sigh* -____-

[@prateekgurjar1651]

All you need to do is multiply diagonally and subtract

[@patrickjmt]

@pabloMTv loooooooooooool

[@SMEXIIDANNY]

Thank you so much!

[@patrickjmt]

@XUnrealpkI i contacted him a couple of months ago about working together (before i knew anything about his big grant), but never heard back. i guess he was not interested!

[@dazede]

hey I need to thank you so much as you helped me to pass my math course!! THANK YOU! myc teacher spoke alien language but you translated it to normal speech.

[@michaelgarcia2050]

That's a positive 4, not a negative 4.

[@kkdimitra]

thank you patrick :)

[@patrickjmt]

glad i could help :)

[@patrickjmt]

@TheKaveshan : )

[@qwertyfshag]

I watch your videos because I hate math. Does that make sense? Anyway. Great explanation

[@RKzero10]

So, does this mean I can dodge bullets?

[@iTechno43]

Whats the difference between the determinant of a matrix and the inverse of a matrix !

[@pabloMTv]

Oh dear patrickJMT, you have yet to f5 my mind with every video you upload, sometimes even ctrl+N :)..

[@AsuusG72]

Very simple tutorial. But what to do if i need to find the determinant of n matrix. For example I have the 3*6 matrix, how can I calculate the determinant in that case? Thanks for the respond!

[@13loodLust]

I had to learn this BEFORE you posted this vid for calculating cross products... good vid as always!

[@RebekahJoya]

hello [

[@kamalrazarford2838]

Thank you very much,it's helpful for me..............

[@RapidShot48]

@patrickJMT Your videos are amazing, i was wondering if you could make a video about how to create and solve word problems about adding, subtracting, multiplying and dividing functions Thank you!!!

[@mr.majesty6767]

👍

[@lordkarlos1]

Thanks bro now I understand

[@bestkidguy96]

I have a question: How does finiding the determinant help me solve a matrix simulatious equation???

[@mkayzondy]

you are a life saver

[@jonr_15]

You are a freaking genius!!!!!!! Thank you for the great vids!!!! :D

[@3dartstudent973]

Thanks for the clear info. one question, can we find the varible x in matrix if we don't knew the value of determinant?

[@ohsocool101]

wow awesome.

[@Intahab]

Thank u

[@Naioki4]

*could

[@xxHEADSWILLROLLxx]

My Honors Pre Cal test is tomorrow......thank you so much

[@michaellopez6095]

....if you add 18 on both sides wouldn't that make -2W =52 : /

[@SoulReaperRX]
