# Example of a moving Frenet basis ({{math|'''T'''}} in blue, {{math|'''N'''}} in green, {{math|'''B'''}} in purple) along [[Viviani's curve]].

#<li value=2> On the example of a [[torus knot]], the tangent vector {{math|'''T'''}}, the normal vector {{math|'''N'''}}, and the binormal vector {{math|'''B'''}}, along with the curvature {{math|''κ''(''s'')}}, and the torsion {{math|''τ''(''s'')}} are displayed. <br> At the peaks of the torsion function the rotation of the Frenet–Serret frame {{math|('''T''','''N''','''B''')}} around the tangent vector is clearly visible.</li>

#<li value=3> The kinematic significance of the curvature is best illustrated with plane curves (having constant torsion equal to zero). See the page on [[Curvature#Curvature of plane curves|curvature of plane curves]].</li>
