Vectors: Scalar Multiplication

Показать описание
In this video I go over scalar multiplication for vectors. The idea behind scalar multiplication is wanting to multiply a vector by a real number c such that it becomes shorter or longer but in the same parallel direction. In other words, the real number c "scales" the vector. And when multiplying by a negative number, the vector flips in the opposite direction. When dealing with negative vectors, we can visualize this by subtracting vectors using the Parallelogram or Triangle Laws. I also go over an example to illustrate scaling and adding vectors.
