C++ OpenGL Tutorial - 3 - Math Crash Course (Vectors)

In this video, we go through the base concepts of vectors. See the timestamps for a list of covered topics. I didn’t explicitly prove that scaling a vector scales its magnitude, but it’s an easy proof to show that ||k*(a,b,c)|| = k*||(a,b,c)|| by factoring out a k^2 from the square root in the distance formula.
