GetDirection(l)
l
-
Line; Line defined in Student[MultivariateCalculus]
Vector; Direction Vector of the line
The GetDirection command obtains a direction vector of the line.
The direction vector is not necessarily simplified.
withStudentMultivariateCalculus:
l1≔Line3,2,1,2,−3,5:
GetPlotl1
GetRepresentationl1
t·2−35+321
GetDirectionl1
2−35
l2≔Line2,0,0,−4:
GetPlotLine2,0,0,−4
GetDirectionl2
−2−4
The Student[MultivariateCalculus][GetDirection] command was introduced in Maple 17.
