A circular helix in xyz-space has the following parametric equations, where θ ∈ R.
x(θ) = 4 cos θ
y(θ) = 4 sin θ
z(θ) = 3θ
Let L(θ) be the arclength of the helix from the point P(θ) = (x(θ), y(θ), z(θ)) to the point P(0) = (4, 0, 0), and let
D(θ) be the distance between P(θ) and the origin (0, 0, 0). Let L(θ) = 10. Which statements do hold?
