Is there anything that this guy can't do ?? I mean, he's literally everything a student need no matter what stage the student is. Big thanks for you ❤

[joshkramer]

I cannot even count the number of times this channel has saved me

I've been watching your videos since high school, and as well as my first semester in college learning Calc 2. Can always count on your videos to give me a refresher and even reinforce topics my professors did not cover well. You're the goat

[MisterBinx]

Doing finite element analysis and forgot a lot of these simple rules even though I got an A in linear algebra. Thank you. These refreshers help a lot.

"hopefully at this point your're seeing a pattern..." - me not seeing the pattern and feeling dumb. hahaha

I have a test tomorrow and this saved me!

life saver!!! My 5 hour math exam is held tmrw, and this was crystal clear, thank u! Luv from Sri Lanka❤

[sapphiremichi]

I have my IGCSE in a few months and my teacher hasn't taught me any of this yet. This saved me so much stress. Thank you for this beautiful video!

I've never understood matrices this easily ! Thank you very much

[jck]

Thanks for the quick explanation! Needed this for a C++ assignment as the last time I had used this was 2 years ago in high school.

Normally id sleep in a maths class, i am not even a maths student but found this interesting to learn at age 30.

[kingaj]

I missed up my school classes when our teacher was teaching this ...but Np you are teaching it far better ..Its just amazing
YOU ARE AN AWSOME TEACHER
