Some Vector Things
Author:
Steve Phelps
Drag the vector around by either dragging points A or B or by clicking on the vector and dragging it that way. Why are the coordinates what they are?
Drag points A, B, C, and D to change the orientation and length of the two vectors. The dot product of the two vectors is shown.
When is the dot product as large as possible?
When is the dot product as small as possible?
When is the dot product zero?
What other questions would be cool to answer?
Drag points A, B, C, and D to change vectors u and v. Vector w is the sum of vectors u and v. How does this sum work?
