Observing the Tangent Vectors of a Vectors Valued Function
Below shows the graph of a vector valued function, but a vector values function is more than just a static graph. If you hit the Animate button, you will see the tangent vector move and change as time, t progresses. You can also choose to observe the unit tangent vector.
