Tangent line and normal plane to a trajectory in the space

This applet illustrates the computation of the tangent line and the normal plane to a trajectory in the space.
  1. Set the point where to compute the tangent line and the normal plane using the slider of .
  2. Check the box Tangent line to plot the tangent line to the graph of at the point and to show its equation.
  3. Check the box Normal plane to plot the normal plane to the graph of at the point and to show its equation.
Enter a new vectorial function an repeat the previous steps.
