# The Vector Dot Product

We learned how to add and subtract vectors, and we learned how to multiply vectors by scalars, but how can we multiply two vectors together? There are two ways to do this, and one of them is called the dot product. Let’s learn how to find the dot product of two vectors now!

1. thanks dave. ur a king.

2. Wow this lecture is very simpler and zero time wasted.
In less time this makes worthy use of time.
Thank you

♥️♥️ From india

3. Thank you for your video

4. am I the only one who finds the intro music annoying?…………..im thankful for the video tho

5. 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.

6. Help ful

7. thank you professor dave i love you

8. Interesting video

9. That was a GREAT explanation. I learned so much!

10. Ugly number 😂😂😂

11. Very useful. Thank you so much

12. Vector OH YEAH

13. Thank you very much prof Dave, your videos honestly help me to ace my classes.

14. 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. <3

15. Thanks. after checking several explanations, that finally made me understand.

16. masterly class! thank you teacher!

17. Thank you so much. You explained different formulas that my teacher explained in 43 minutes into just 7 minutes!

18. Thanks a lot professor you really explained very well

19. Thanks , ranbir kapoor !

20. Reckon this video can also be included in the linear algebra series

21. Thank you professor. You made dot product as a pice of cake to me:) love your explanation<3

22. Hey you , the chemistry jesus ..

23. Ok, so we can multiply vectors in a way that gives a scalar value. Was this video meant to show how to derive an angle between two vectors using a dot product? What does it physically mean to compute the dot product other than to derive the angles between the two vectors???

24. Good!

25. God loves this Dude

26. Thank you sir, I am ready for my exam 😀

27. Dev. I am impressed. Short and clear.

28. But what does mean the scalar product in real life.
What the scientists were thinking about when they decide to make scalar product
