Student[MultivariateCalculus]

  

AreSkew

  

determine if two lines are skew

 

Calling Sequence

Parameters

Description

Examples

Compatibility

Calling Sequence

AreSkew(l1, l2)

Parameters

l1, l2

-

Line ; Line defined in Student[MultivariateCalculus]

Description

• 

The AreSkew command determines if two Line objects are skew.

• 

Lines are skew if they do not intersect and are not parallel to each other. Since lines in 2D space always either intersect or are parallel, this command always returns false for lines in 2D space.
