Plotting and Animating 3D Vectors

I'd then like to table the different vectors for different times and create an animation of the evolution of the vectors.

How should one go about it?

The expression I essentially wish to plot is:

$$ \vec{n}(\tau) = \Big ( e^{- \gamma(\tau)} \sin \theta \cos \phi, e^{- \gamma(\tau)} \sin \theta \sin \phi, \cos \theta \Big ), $$

where $\gamma$ is some function of the time, $\tau$.

The functions you need to use are E, Sin, Cos. You put your formula inside an Arrow statement, inside a Table statement that varies time. Use Graphics3D to show everything. Put a Sphere in the background with low Opacity. When it all works, wrap it in an Animate. – Nicholas G Nov 20 '16 at 11:41

Have you seen the Bloch vector animation near the end of this post ? – LouisB Nov 21 '16 at 05:46
