Vectors
A new lesson is available on the Linear Algebra page that will determine the full math work and answer of the following given 2 vectors A and B:
A  length/magnitude of A
B  length/magnitude of B
A + B
A  B
A * B  Dot product
Distance between AB
Angle $\displaystyle \theta$ between A and B
Simply enter vectors in a stacked format as shown on the vector lesson here:
Vector Basics
Please let me know if you want enhancements or if you see errors.
The search engine will pick up the keywords vector(s), angle, product, length, sum, difference.

This lesson has been enhanced with a "Relationship" button, which shows if 2 vectors are orthogonal (perpendicular), parallel, or same direction.
