Vector Projections - Example 1

Vector Projections - Example 1. In this video we show how to project one vector onto another vector. Projection vectors have many uses in applications - particularly in physics applications.

You don't understand how much I needed this. Literally, the 3rd day of class and my professor confused the hell outta me. But now I understand. Thank you so much! New subscriber frfr!

Hey Devin, I really appreciate your lectures. You do a great job presenting the material in an accessible way.

This is so simple that at university we never bothered with it (I did Mechancal Engineering - the Maths was 10 times harder than this). However I am now doing it with my high school students. They use other terminology but obviously the working is the same. Well presented, thank you.

Thanks for this explanation, it is the first time I have understood the dot product concept. Your style is clear and concise. And the video is a good length.

[tanisaguinsin]

You explained the concept really well! Thanks for this :)

Its really nice explantion keep going.I am a game developer but most game developers don't know the basics too.Your video explains clearly also if you can teach all the vector mathematics concept visually it will be awesome.Anyway this is really a good explanation.

Thank you for the helpful video. Great to see an example!

Very nice explanation, good for dummies like me. Thx

Great video, I am seeing geomtry analytic and it helped a lot

In the dot product, why are you considering the cosine of the angle between the two vectors? That's the formula right? u*v*cosine(theta)

Great video! I am not too familiar with vectors and I cannot figure out how to work this problem if the vector starts at something other than (0, 0). For example, Lets say that everything was translated up 1 and over 1. The coordinates would be 3, 8 and 0, 5 i believe. How would I work out the problem? Thanks!

[victorbanik]

in the formula you have given 2 modulus signs like ||v||^2 but modulus sign is once enough like |v|^2 ????
