Coding Math: Episode 6 - Vectors, Part I

In this video, I cover the basics of vectors, which will be useful as we get into coding various physics principles. This one is a few days late due to the holidays and the fact that I had to rethink the scope of the video several times. It started off as a video about velocity, then a video about coding vectors, and finally just reduced it to vector concepts. The next video will get into coding vectors.

I am very sad that you did not continue the series, this is priceless!

My brain decided to RD \Math\Trig /S /Q sometime in the last two years, so I hit a wall when I needed to implement unit motion in my game. Episodes 5-7 were great refreshers, thanks so much!

best series ever for math and javascript! Thank you for sharing your knowledge

you are awesome..u made coding math really simple

The visual demonstration of vector subtraction was a little confusing (it seems like you could keep the "head to tail" like in addition, but just go backwards/"reverse" basically), but the math part certainly isn't.

One of the clearest explanation of vectors I have seen.

Great video!!! I really like the explanation you give on vectors; I just have one issue: Vectors do not have a position.  the point that the head of the vector is pointing to is not part of the vector and it does not represent the vector.  this can be proven by the fact that if you move the vector to a different location in space and keep its magnitude(length) and direction(angle) it will be the same vector regardless of it's position.  If a vector had position then by moving it would mean you would had a different vector.  It would be more accurate to say that the vector can be used to find a point in space relative to the point in space it started from.
