extracting start and end coordinates of vector
Answered
Hi Guys,
If I have a vector defined, is there a way to extract the start coordinates and/or the end coordinates? (I'm thinking of something similar to using x(A) when you want to extract the xcoord of point A, except for vectors). I'm trying to avoid having to define a point at the beginning and end of each vector when I'm drawing vectors "tiptotail". Cheers!

Hi,
Let vector u
x(Point(u,0))  y(Point(u,0) )
x(Point(u,1))  y(Point(u,1))
Hi,
Let vector u
x(Point(u,0))  y(Point(u,0) )
x(Point(u,1))  y(Point(u,1))
The coordinates of vector define the horizontal and the vertical translation. It hasn't got start nor end coordinates. As for points you can use x(u) and y(u) to get these horizontal and vertical translations separately.
