One day before my exams... I was literally frustrated.... My whole vector syllabus wasn't completed.... This is the bestest lecture I've ever seen.... Very helpful I'm now ready for my exams... Thanks to you💜
I think a whole world of people molested by their giftless maths teachers at school and college gathered here to find relief and finally understand what the teachers were not able to explain. Thanks for bliss man. Amazing job.
Thank you so much... For making this concept easier for us to understand. The truth is normal teachers style of teaching is confusing and somewhat overwhelming because I notice that they introduce so many concepts that they don’t establish connections bet them so a big thanks to you sir for making this really simple for us🥺🥺🥺💕😭
Im a VFX artist and ive only known how to input and output my functions to get result and now thanks to you im learning whats actually going on in my code.
I understood the topic somehow when I read it from the book, but this video gave a more intuitive and clearer explanation! Awesome job, Professor, thank you so much.
Wonderful explanation. Very clear and succinct. I would only add the 2d visual notion that "vector dot product" (of two vectors) is obtained by multiplying the length of either vector by the "projection" of one vector over the other (think of laying the angles vectors flat on a table, and having a lamp illuminating from "above". You would multiply the length of the vector laying flat by the length of the shadow of the companion.).
first day of college and i couldnt understand a thing from my prof and here i am. i wasnt able to answer any of the questions he asked but now i realize it was such an easy subject
Btw Dave, I have cracked vector rotation, relying entirely on scalar and dot products. My solve can also be extended to higher dimensions, as I also standardise with the right-hand rule. I also note that you can find the angle by looking for one co-ordinate on a unit circle, and measure the area beneath it and add the triangle adjacent to it and with its opposite point at the origin, and multiply all by two, to get the answer in radians. But if degrees are your fancy, you gotta multiply instead by 90/π! Or…you could just use a protractor. Et voilà; no calculator needed!
thanks, taking quantum mechanics and wasn't paying attention to the plus sign during lecture. now things make more sense. Scalar Product is Dot Product to find a Scalar Value.
Thank you Professor...I am doing 3d graphics engineering and needed an explanation on why the guy in the video was using the .product over the lengths of a and b to determine if an angle was withing 90°
Thank you Dave! This is the first video of yours I've seen! It was very helpful and clear! I appreciate the work you did in making this video! Have a great week!
I thought that the dot product is always positive because the result is in absolute value, as written our module. Maybe there is just a problem in the publishing of our modules. Thank you for this video, all things are clarified. 💯
The dot product is always a scalar, but it is not always positive. Dot product means multiply corresponding components, and add up the various results. If some of those components are negative, you very well could get a negative dot product.

@@Th3Siam / it’s not, you just weren’t smart enough to get into a good college or uni. Your loss
This is the only place where I can finally understand this. Even books and lectures can't do this. Thanks, Professor.

I'm grade 11 student, from ethiopia I like and understand your lesson ❤❤❤❤
Mee too I have got all in that lesson
Me to
this guide is absolutely perfect. I was lost in class for a week and this helped me catch up in less than 7 minutes
Im a VFX artist and ive only known how to input and output my functions to get result and now thanks to you im learning whats actually going on in my code.
Perfect timing! Im doing this in my physics class
Wow this lecture is very simpler and zero time wasted.
In less time this makes worthy use of time.
Thank you
♥️♥️ From india
Industry professional returning to school and having to refresh my memory on all these math concepts I learned 10 years ago. I can't thank you enough!
I understood the topic somehow when I read it from the book, but this video gave a more intuitive and clearer explanation! Awesome job, Professor, thank you so much.
thank you math jesus
Ur gay
I have been watching your videos since 2015 and I still run back to this channel for better understanding of some concepts in math.Long live Prof

Perfect explanation Professor! It is very useful for me as a game developer! Thank you so much!
Your comprehension questions are really helping me to understand this better.
Thank you so much. You explained different formulas that my teacher explained in 43 minutes into just 7 minutes!
i got my uni exam in a week and you're my saviour
Literally watched this during lecture. Explained everything that professor couldn't in 2 hrs in just 6 mins.

I am really thankful for people like you. You saved me from studying 8 pages of notes.
Thanks for the mathematical warmup
This will be very helpful for the graphical/game dev stuff with C
Thank you very much prof Dave, your videos honestly help me to ace my classes.
Ton of information in this short video - just the way I like 'em! Thanks!
Can you imagine? Am learning this in just some few minutes 😯
Kudos sir👍
Thank you so much....I love that you teach without wasting any time....🥰🥰
This is the beat math working out that I have every seen.
This is the BEST I swear. New subscriber.
seriously man even a 2 year old can understand this thing . so clear crystal explaination love and prayers from india ❤
This is the best channel for explanation the lesson and prepare for exams thanks❤
Wow this is the right person for me. Prof. You are the best
I watched other videos before this one ,and trust me this is the best and the most comprehendable
The explanation is short but its a huge concept to grasp.
Thank you Professor...I am doing 3d graphics engineering and needed an explanation on why the guy in the video was using the .product over the lengths of a and b to determine if an angle was withing 90°
Dev. I am impressed. Short and clear.
The BEST answer i got from all of the videos I have watched.
best teaching method friendly
Bless you sir. Studying for my high school math teaching cert and it’s gone from 0 to calculus in one chapter.
Thank u sir for ur video.... I'm now able to do it before anyone... even my teacher... thanks again 🤗
I maybe a little overwhelmed with understanding here, but sir, you are a hero 🫡
This lecture is superb.I enjoyed every bit of it . Thanks sir and more grace from God, for extraordinary intelligence .
Nice clarification
my teacher plays ur videos in class and i can see why
Excellent video Prof Dave. Thank you
Excellent teaching.❤️from India
Very good explanation. Thanks and best wishes from Sweden 🇸🇪
what a great video! I love to see where formulas come from before using them!
you made that easy for me professor i love your channel
I have been searching for so long for some details like this
May your days be filled with happiness and pleasures
Great video, thank you! Haven't done this since the 80s.
thanks dave. ur a king.
Thanks a lot for this video, i cant reallu thank you enough, for explaining me this so quickly.
Amen
I FINALLY understood this topic thank you so much!!!
first video and im already a fan
thx bro, solved my questions in a mere one minute.
I knew how to do this, but not why. Thanks for the lightbulb moment!
🙏 thankyouu!! This is such a well constructed and insightful video - probs the best I've seen on this topic.
It's last night before the exam and then I found u... much luv❤
Thank you Dave! This is the first video of yours I've seen! It was very helpful and clear! I appreciate the work you did in making this video! Have a great week!
Why my calculator is giving me 4.1 instead of 4.108 ? Great video Mr Conversano.
Math Jesus
Theres always that one guy in every vid that says "blabla jesus".
Amen tho
Amen
lmao ... I thought you were going to say "math Guinness"
Pretty sure he's Jewish too.
@@EmilJustinCerio I love Jesus. He cured me from wanting to lust after women
That was a GREAT explanation. I learned so much!
Thank you, great quality and easy to follow!
Thanks for the video, it's really helpful.
Clearest explanation ever 👍🙏
Thanks, because of you I’m learning a lot (I am only in year 9).
thank you kind sir, online class isvery hard

Thank you professor dave
thank you, professor. you are a great guy
was never taught this in school but need it now
thank you professor dave i love you
Thanks. after checking several explanations, that finally made me understand.
You make it soo easey
professor, very informative lecture. Thanks.
Can you post a video for understanding Eigen Vector and Eigen value?
Thank you sir for teaching me this
God bless you
I love this video! Just one question, how do I convert 1.46 rad into 84 degrees?
theres a formula for converting rad to degree and degree to radian
radian to degree 180/pi
degree to radian pi/180
i was searching for 30 minutes last i find you my scientist
Would love some videos to explain the dot products application and uses. Instead of just how to solve a problem.
Hey, thanks for your videos. They help me a lot.
Thanks you Dave😍.
You are better than my physics teacher❤️👑
I just wanna say thank you
I'm nigerian
Well done it was very useful professor
Thanks sir for removing my doubt.
extraordinary explanation
thanks
Thank you! Very well explained
Everytime I see his face I can already hear "He knows a lot about a kinds of stuff. Professor. Dave. Explains." 😂❤😊
Very useful bro!!!
Thanks dave from now I will be one of your subscribers 👍😎😎
Bruh, he explained this so much better than my lecturer.
Excellent Teaching
India : we studied this in school
Foreigners: we studied this at college 😅
Then what about icse
Don't think it matters anyway
What the hell. How can you expain this so clearly in such little time when i've spent days trying to get this? I hate books.
