❖ Vectors - The Dot Product ❖

In this video we look at finding the dot product of two vectors.
Note that the dot product of two vectors is merely the product of the respective components of each vector all added together. Therefore the dot product is a scalar; that is: the dot product is just a number.
What does this number tell us exactly?
One useful result is that if the dot product of two vectors is zero then the two vectors are orthogonal or perpendicular. Likewise, if two vectors are orthogonal / perpendicular, then their dot product must equal zero.
Likewise we can use the dot product and the magnitudes of two vectors to help us find the angle between the two vectors.

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

[patrickjmt]

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.

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.

[madeinsa]

always come here when times are hard cos i know Mr Patrick will rescue me. THANK YOU SIR

[patrickjmt]

@SynpaticInc happy to help! : ) not a ton of physics stuff, just stuff mainly related to vectors

[augustus]

I was a kid when you uploaded this... But after 10 yrs now I am watching it... It's very helpful Sir

[johngreen]

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

[kennethhowell]

You can always tell when someone knows what they are talking about. They explain it and you understand it immediately. Thank you!

[MPV]

you helped me last year with Calc 1 + 2, now I'm onto multivariable calculus and you're at it again. I love you.

[kevinhowley]

You'll be the sole reason I pass my exams.

[dont_touch_my_cupcake]

It's been 12 years but it's still super helpful. Thank you so much !!
Also, I noticed he's left handed!!!

[Gohon]

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!

[yuliaaaaaasup]

Thank you for your easy explaination :)
I have exam tomorrow and this is really useful.
Nice handwriting btw! Very tidy <3

[patrickjmt]

@rustyshackleford54 there is a video on that somewhere.... if they are parallel they are simply multiples of each other!

[nathandavis]

You're awesome. I'm reviewing for IB HL exams, and you're extremely helpful.

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.

[patrickjmt]

@theDgrader no problem, happy to help

[hansolo]

I tried reading the wikipedia page and it was a freakin mess. This video, I understood within the first minute. Thank you!

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.
