Here is a short bit of code that shows scalar addition and scalar multiplication (between two scalars). Click the “play” button to run the code and the “pencil” to edit it.

Anyway, the same can be done with vectors, but it is important to remember that vectors are not scalars. To help with this distinction, I will write variables that represent vectors as different ...

Product of a scalar times a vector A scalar (s) times a vector A equals sA, which is also equal to As. Multiplication of two vectors Let's look at Fig. 4. Multiplying A times B will result in C, whose ...

Expressions are obtained for the resultant of n vectors whose directions are completely random in s dimensions, but for each of which the distribution of the scalar square is given. This is most ...
