vectors
... A vector has both a magnitude and a direction. A scalar has only a magnitude, no direction. Vectors are indicated by an arrow over the symbol, e.g. the velocity vector is written as v . Vectors are represented by arrows. Length of arrow = magnitude of vector. The negative of a vector b is called b ...

... Now we need to look at the diagram where two angles are indicated. We want to calculate 1 so let’s do some trigonometry. We use the parameters in the diagram as well as the components of a and b which are not specifically shown but we all know what they are. (Right??) Now it gets a bit sneaky. Noti ...
