Vector addition

Instructions on how to use the animation below:

The following java applets try to show how to add two vectors, A and B, into a single vector C:

C = A + B = B + A

How to play:

There are two methods to form a vector:

1. Left click anywhere inside the window to form vector A or B (starts from the origin)

2. Drag and lift the left mouse button to form vector A or B. The vector will move to the origin after you release the mouse.

The program will show you how to add two vectors A and B into C:

C = A + B or C = B + A

Press the Reset button or right click the mouse button to reset. Parameters are reset to default values.
Select the info checkbox to show more information, like the X,Y components of each vector.

How to form a 3D vector:

Moving the mouse within the window will establish a vector on the X-Y plane.

Left click the mouse, then drag it up/down to change the Z components. Release to create the vector.

When you form two vectors A and B, another vector C = A + B will show up.

Drag the right mouse button to change the viewing angle.

Drag near the origin to change the displacement of the camera view.
