Vectors are entered as <2,3>. They can be added, subtracted and combined with a point. See regional issues
For example:
(-2,-3) + <4,7> + <3,-3> - <4,0>
Polar Vectors
If you prefix one of the vectors/points with a P, the graph tool will interpret the points and vectors as polars. You must enter any angles using the current angle measurement (degrees or radians).
p(1,pi) + <2,pi/3> - <6,-pi/4>
Constants
Vectors can contain constants which are discussed later in this manual. You can enter a vector of <-3a,b> for example.
Regional Issues
If you use a comma as a decimal point (eg 3,2) you must use a semicolon to separate the two coordinates.
(-2;-3) + <4;7> + <3;-3> - <4;0>
