Cross product

Syntax

crossP(Vector1, Vector2)

crossP(List1, List2)

Examples

Vector calculations

Vector operations and commands work as shown in the example.

norm, unitV, dotP, crossP

Vector perpendicularity and parallelism

Vector problems can be solved by combining the solve command with vector commands. The image shows examples of perpendicular, parallel, and same-direction vectors.

Three points on the same line

Whether three points lie on the same line can be examined using vectors. If vectors AB and AC are parallel, the points lie on the same line. Parallelism can be checked using the solve command or alternatively using the cross product.
