Applets
Components of a vector: Shows a rotating, changable vector in three dimensiona. [Walter Fendt]
Vector toolkit: Three applets illustrating free operations on vectors. [ETSU]
Operations on vectors: Shows how the sum, difference, and projections on vectors change as the vectors move. [MIT]
Norm applet: Shows how the Pythagorean Theorem is used to calculate norms of vectors. [ETSU]
Vector toolkit: Two applets illustrating the dot product. [ETSU]
Vectors in 3-space: Shows several examples of vectors in 3-space, allowing for rotation. [Maths Online]
Curves in three dimensions: Plot any parametric curve in space and see the position, velocity, and acceleration vectors. [MIT]
3D parametric plotter: Plot any parametric curve in space and see the plot plots. [ETSU]
