Comparing Functions Winch of the following vector- valued functions represent the same graph?

(a) r(t)=(–3 cos t + l)i + (5 sin t + 2)j 4 + 4k

(b) r(t)=4i + (–3 cos t + l)j + (5 sin t + 2)k

(c) r(t)=(3 cos t– l)i + (–5 sin t –2)j + 4k

(d) r(t)=(–3 cos 2t + l)i + (5 sin 2t + 2)j + 4k

solve for unknown: S,P,L,G,M,R,C,T
