as with anything, you must practice yourself! i watch my videos when i forget stuff though - i would rather listen to me than to read : ) works for me at least! that is why i make all these videos... so that i can teach myself when i forget
I attend a lecture and leave knowing nothing. I just have a paper full of notes and mind full of anxiety. I come home after the lecture and desperately search for help. I find your math content. I find peace of mind and a sense of accomplishment after learning various mathematical concepts. That's been the story of my mathematical academic career so far. Thank you for essentially being my professor.
My profs are good, but what I don' like is they tend to beat around the bush a lot. I like these videos because they're straight to the point. I feel like classes would be half as long if my profs just said what they had to
Why can't you be my professor? Instead, I get an old man screaming at me for not speaking the language of Physics. Seriously man, I am trying my best here.
+The Duke This is what makes me glad that I chose to complete my Lower Division Maths at a Community College before transferring to University. The lecturers here for math are some of the best I've ever had and I think I will ever have. I initially hated math coming into college but from Intermediate Algebra to Calc II (now), I've grown to love mathematics. PatrickJMT helps a lot with reviews for me or if I need a quick refresher.
I'm glad I found your videos when I was doing math during my PreCalc year. It's been helping me get all the way through Calculus. Not only that, but now I'm still finding these videos helpful and I'm studying Physics!
Praise be to the man that allows his dynamics to be paused and written down and dwelt upon. If I could pause and rewind and search my professors mind, then I would be praising his glory too. Thank you for pause-abale systematic explanations they help shed light.
What the crap do I go to an hour long class for ? you just explained what the COLLEGE professor took a million and a half years to say and I still didn't get it. You rock dude
The part describing finding an angle between two vectors using dot product is super handy. I'm using it in Unity to calculating object transforms in 3D space. I really can't thank you enough!
Thanks a lot, you def. have what it takes to teach! I am programming my Vector2D class in C++ for my 2D game engine right now as i watch this video! Thanks again!
I used to watch your videos around 5 years ago when I took my first crack at engineering. Unfortunately no amount of tutorials, as clear and instructive as they may be, can fix a bad student. Here's hoping things go better the second time around.
I was ready to hit my head against a wall when I couldn't get what my professor was talking about. Your videos have literally saved my life! Thank you soo much! :]
@svalmazan if you mean the a dot b = a b cos theta part, it is proved in any calculus text book; basically one uses the law of cosines to arrive at the result
Pythagorean theorem can be extended to to encompass three numbers. simply do |x| = sqrt (1^2+4^2+7^2) and do |y| = sqrt(1^2+2^2+3^2). This rule can be assumed if you simply look at it on a 3D graph.
Inside of the first 30 seconds you explained precisely what several hundred thousand people loaded up this video to see. Thank you, and good day. You've earned a like.
holy shit man, your videos are awesome i was so confused before, but now that i've watched your videos i might pass my vectors test tomorrow after all and make it to university :D
If vectors are orthogonal in a geometric sense then the angle between them is ninety degrees. The cosine of ninety is zero. Thus two orthogonal vectors should have a zero scalar dot product.

that and a lot of professors just tell you how to do something without explaining why you are doing it and what you are getting/finding
than they would only have half of their salary is a game and we are the ones being played

what college do you go to

I was a kid when you uploaded this... But after 10 yrs now I am watching it... It's very helpful Sir
always come here when times are hard cos i know Mr Patrick will rescue me. THANK YOU SIR
@SynpaticInc happy to help! : ) not a ton of physics stuff, just stuff mainly related to vectors
I'm glad I found your videos when I was doing math during my PreCalc year. It's been helping me get all the way through Calculus. Not only that, but now I'm still finding these videos helpful and I'm studying Physics!
you helped me last year with Calc 1 + 2, now I'm onto multivariable calculus and you're at it again. I love you.
You can always tell when someone knows what they are talking about. They explain it and you understand it immediately. Thank you!
you are most welcome :)
Praise be to the man that allows his dynamics to be paused and written down and dwelt upon. If I could pause and rewind and search my professors mind, then I would be praising his glory too. Thank you for pause-abale systematic explanations they help shed light.
You'll be the sole reason I pass my exams.
ur the number one tool when it comes to cramming for my tests! thank you!
Better than Khan.
The point isn't what's better. If you understand then that's what matters.
waaaaaaaaaaaaaaaaaaaaay better than khan
Jon G yea
just curious whats wrong with khan academy?
Khan takes forever to explain something
It's been 12 years but it's still super helpful. Thank you so much !!
Also , I noticed he's left handed!!!
What the crap do I go to an hour long class for ? you just explained what the COLLEGE professor took a million and a half years to say and I still didn't get it. You rock dude
You're awesome. I'm reviewing for IB HL exams, and you're extremely helpful.
Thank you for your easy explaination :)
I have exam tomorrow and this is really useful.
Nice handwriting btw! Very tidy
I'm most amazed by how you write with your left hand without rubbing it out as you go along!
Awesome video I subscribed.I learned more from you from 1 video than I did an entire year with my math teacher
As I prepare to graduate this coming May..I look back at these videos and Patrick I want to thank you for getting me through Cal I - III...
You teach so much more clearly than my lecturer... So much easier to understand now
Thank you so much! This explanation was far clearer than the one in my textbook.
The part describing finding an angle between two vectors using dot product is super handy. I'm using it in Unity to calculating object transforms in 3D space. I really can't thank you enough!
Thanks. These videos will get me through this semester
Thanks, Partrick, I've passed my calculus because of your videos!
Just helped me pass my final exam with this vid, thanks a ton man!
i was doing my calculus final work and i forgot how to do this stuff and you.saved.me.soooo.much time i cant thank you enough:)
Your teaching is perfect, thanks for sharing these videos!
Thanks a lot, you def. have what it takes to teach! I am programming my Vector2D class in C++ for my 2D game engine right now as i watch this video! Thanks again!
indeed solved my doubts. thank you for your video!
Wow an hour and 15 min class in 7 mins.... and better than the prof -.- Thanks!!!
I used to watch your videos around 5 years ago when I took my first crack at engineering. Unfortunately no amount of tutorials, as clear and instructive as they may be, can fix a bad student. Here's hoping things go better the second time around.
Midterm today... I bow down to you. ALL HAIL PATRICK!
Oh my god, you just saved me from flunking my test. I did NOT understand a thing about this until now!
you are SO much better than my professor, i think i will just stop going to class and watch your videos for 2 hours instead
I tried reading the wikipedia page and it was a freakin mess. This video, I understood within the first minute. Thank you!
@theDgrader no problem, happy to help
Patrick always simplifies the complex.
Thank you so much! :)))
I was ready to hit my head against a wall when I couldn't get what my professor was talking about. Your videos have literally saved my life! Thank you soo much! :]
The first minute was all that i needed but that really helped me understand physics!
man seriously, anytime I have confusions on calc your video clear it up....keep it up...=)
@svalmazan if you mean the a dot b = a b cos theta part, it is proved in any calculus text book; basically one uses the law of cosines to arrive at the result
Great video, thanks! By the way, I'm left handed and super jealous of your handwriting.
thanks PJ, i went through the theory and got bogged down, you have helped allot in understanding a few gray area's.... thank you sir
Much appreciated you dear for making dot vector simple to understand
@rustyshackleford54 there is a video on that somewhere.... if they are parallel they are simply multiples of each other!
Pythagorean theorem can be extended to to encompass three numbers. simply do |x| = sqrt (1^2+4^2+7^2) and do |y| = sqrt(1^2+2^2+3^2). This rule can be assumed if you simply look at it on a 3D graph.
JESUS you make this sound so much more sense than my professor! thanks patrick
Thanks so much! I finally understand the Dot Product!
cheers m(4+4) you have help me with my math c exam on Wednesday :)
Thanks, my math teacher is going to teach this to us tomorrow, :) I will probably get a head start on this! Thanks for the video.
Man, I can't even tell you how much seeing you do this helped. Definitely heading to patron to show some support.
Omg thank you for this video it helped me understand what i couldn't in a 2 hour lecture😁
Inside of the first 30 seconds you explained precisely what several hundred thousand people loaded up this video to see. Thank you, and good day. You've earned a like.
way better than khan academy!
to be fair khan academy is great, he and patrickJMT are the best i seen so far
in my opinion the fact that he does it by hand, really does make it better
This is a clear and concise explanation - thanks a million.
Awesome! You're a member of the master left handed race. Lefty high five!
Thanks so much! Patrick I am going to get 100% tomorrow in my exam!
i dont know why you even upload all these videos but God bless you.
holy shit man, your videos are awesome i was so confused before, but now that i've watched your videos i might pass my vectors test tomorrow after all and make it to university :D
THANK YOU FOR EXPLAINING IT IN SIMPLE TERMS
You are the Math GOD...Why do you like this stuff so much?
Helpful for my test. ^^
Extremely helpful, thanks! I'm subscribing right now for whenever I gotta do my webassignsXP
Thank You SOOO much!
i was slacking with my notes, and didn't have this the dot products and vectors
!thanks
You just explained this like a boss.
Sweet, short and effective! Thanks man👏
thank you my professor cannot explain anything at all
While I'm logged in, I just wanted to let you know that your videos are great. I will do more searching just to watch your vids. Thanks
because a ' x ' means something else with vectors - that notation is used for finding the cross product
Thank you for this. Clear, and concise. Mystery solved!
Please do more Physics Videos!! There just as good as you're math ones!
It helped me a lot sir!!!!!!!Tqq soo much!!!!!!🙏🙏
you are officially a student at patrickjmt U
0:38 i KNEW it was "if and only if" rather than simply "if" ...should've corrected my Physics teacher right away...anyway, thanks Mr. Patrick!
We meet again but now i'm at the UW Seattle. Thank man you ROCK!!
ha, i would like to visit seattle again
i really love your tutorials.
Thank you thank you. You’re way better than my prof
This is very useful and comprehensive.
Oh at the end of the video when he mentioned orthogonal, just magic. Verbatim what I needed to know. Gorgeous
thanks! normally i have the handwriting of a 5 year old, but i try to keep it neat in the vids! : )
This is absolutely amazing! Thank you so much!
You have saved me from math 254. THANK YOU.
Thank you soo much, this is just what I need
great video, thanks alot this helped alot :)
Always thank you Patrick. You are awesome.
glad to help :)
@chromagnonbc well, people tend to always use radians in calculus - that is just the convention.
THANK YOU PATRICK!!!!
you are welcome :)
I think it goes without saying... We all wish we were a student of patrickjmt !
The fact that this guy speaks English and not derka derka makes him so much easier to understand
no problem, happy to help : )
thank you for such clear presentations!
1:19 has your answer. Two R^3 vectors are orthogonal when their dot product = 0 (zero)
wow!!! nice explanation. thank you.
i think you're much more helpful than khanacademy
Thanks man! Good recap! :)
Seriously man. Magician.
answer please : A.(B*A) = ?? whatever A or B how to find it?
A.(A*B)-0 because box ABA IS EQUAL TO ZERO
If vectors are orthogonal in a geometric sense then the angle between them is ninety degrees. The cosine of ninety is zero. Thus two orthogonal vectors should have a zero scalar dot product.
