# AngleVector

AngleVector[θ]

gives the list representing the 2D unit vector at angle θ relative to the axis.

AngleVector[{r,θ}]

gives the list representing the 2D vector of length r at angle θ.

AngleVector[{x,y},θ]

gives the result of starting from the point {x,y}, then going a unit distance at angle θ.

AngleVector[{x,y},{r,θ}]

gives the result of starting from the point {x,y}, then going distance r at angle θ.

# Details • Unless explicitly given as a Quantity object, the angle θ is assumed to be in radians, counterclockwise starting from the axis. (Multiply by Degree to convert from degrees.)
• AngleVector[{r,θ}] gives a vector that starts at {0,0}.
• The arguments of AngleVector can be symbolic. They can also be Quantity objects.
