Two particles moving in space have position vectors at time t ≥ 0 given by r(t)...

Two particles moving in space have position vectors at time t ≥ 0 given by r(t) =< cost,sin t, t > and r(t) =< 1, 0, t > . (Please provide more details thank you )

(a) Describe the particle paths.

(b) Do the curves described by the particle paths intersect? If so, where?

(c) Do the particles collide. If so, at what time(s)?
