You are given an explicit expression for your smooth curve x, so you just need to compute the Frenet data as per the definitions.

You will end up with something like:

T_2=B_1

N_2=-N_1

B_2=T_1

k_2=t_1

t_2=k_1.

Where T,N,B,k,t denote the tangent, normal, binormal, curvature and torsion respectively.

(Carry out these calculations carefully yourself, there could easily be a small mistake in my answer. Haven't done this kind of stuff in a while.)
