Question

Match the parametric equations with the correct graph (labeled I-IV).
(a) x = t cos(t), y = t, z = t sin(t),    t ≥ 0
(b) x = cos(t), y = sin(t), z = 1/(1+t²) 
(c) x = t, y = 1/(1+t²) , z = t²
(d) x = cos(t), y = sin(t), z = cos(2t)

Match the parametric equations with the correct graph (labeled I-IV).

(a) x = t cos(t), y = t, z = t sin(t), t ≥ 0

(b) x = cos(t), y = sin(t), z = 1/(1+t²)

(c) x = t, y = 1/(1+t²) , z = t²

(d) x = cos(t), y = sin(t), z = cos(2t)
