Calculate the Frenet apparatus (T, k, N, B, and t) of the following curves: *a. a(s) = ((1+s)³/2, (1 − s)³/2, s), s€ (-1, 1) - b. a(t)=(e(sint + cost), e' (sint - cost), e') *c. a(t) = (√√1+12,t, ln(t + √1+12)) d. a(t) = (e cost, et sint, et) e. a(t) = (cosht, sinh t,t) f. a(t)=(1,12/2,1√√1+12+ In(t + √√1+12)) g. a(t) = (t-sint cost, sin² 1, cost), tЄ (0, л)
