f(t)=(cost^3(t), sin^3(t));

how do you solve the [tangent T, normal, N, and binormal, B,

 from the curvature k and torsion t of the curve osculating plane] 

above drawn curve? Could you help me

f(t)=(cost,sint,cos2t)

I need necesary commands in order to draw to f( t)...'s tangent at t=pi/3. Could you help me
