Finding the Inverse of a 3 x 3 Matrix using Determinants and Cofactors - Example 3

[aqdjbcr]

been a fan of you my entire college career as a math major. You've been more helpful than any professor. Thank you

[Uskie]

Learning step by step is so much easier than learning from a text book!
Thanks for sharing!

[mojoe]

You should see the way I just tried to do it..

video's like these are getting me through school.

[abedaure]

my exam is literally in 20 minutes. this 5 minute video just saved my life. thank you!!!

[JulieSharp]

Thank you for explaining the concept clearly and concisely! I thought that finding the inverse of a matrix was some kind of magic that could only be performed with a calculator, but now I feel comfortable doing it on my own after watching a five-minute video! This will be tons of help during my math exam on Wednesday. Thanks, patrickJMT!

i honestly would'nt have made it through my math classes without this guy and his videos!

[erfanheterjag]

Thank you a thousand times for this! This is ALOT better than reducing it to an identity matrix

[iguanalegal]

Patrick, seriously, you make my teacher look so dumb... i love the way you teach this problem... 2 blackboards full of matrices from my teacher, you reduced it significantly .. thank you! I GOT AT A- on my test thanks to ya!

[galaxylinds]

You have seriously saved my life. I don't know what I would have done if I hadn't found this video.

[Jasn]

This alot quicker than row reduction and less error possibility thank you mr.

I'm glad I actually missed my Math's lecture about determinants.. instead of sitting there for 1 hour I learned all I need to know in 10 mins..

[kekemamal]

oh GOD you're amazing!! my lecture was not clear to explain this so that i dont even understand what was he said to me bout this subjects.... BUT YOU, i only open this video once and directly i can solve this problem!!! more efficient way to study, INDEED

[teddycliff]

I really love the calculations, thank you for helping me understand 🤗🤗🤗

[AshimShunnota]

Recieve thanks from Bangladesh.Your video helped a lot.

[DewiIndira]

You're god of math, thanks from Indonesia O:D you're better than my college teacher. seriously dude. you're the chuck norris of mathematics

[hgo]

This helped me soooo much ;___; ily and thank you!! 

[phreshstuna]

Dude you Keep up the community service

[behzaddll]

Thanks from Afghanistan!
really good and useful.

[lawrencehernandes]

It's easier if you put it to the left of an identity matrix and use row operations to change the left side into the identity matrix. What you end up having as your right side would be the inverse. You make anything look easy though. Love your teaching methods. You sir are an amazing individual

thank you much for this so musch easier than the way my professor taught it!
