Parameters

l

-

Line ; Line defined in Student[MultivariateCalculus]

p

-

Plane ; Plane defined in Student[MultivariateCalculus]

Returns

• 

list ; A point on a line or plane

Description

• 

The GetPoint command returns an arbitrary point on a line or plane.

• 

This command guarantees that the point returned lies on the line or the plane, but it does not guarantee the location of the point relative to the axis, the origin, or any points provided to Line or Plane constructors.
