The following parametric equations generate a conical helix.
x = t cos(6t)
y = t sin(6t)
z = t

Compute values of x, y, and z for t = 0 to 6π with Δt = π/64. Use subplot to generate a two-dimensional line plot (red solid line) of (x, y) in the top pane and a three dimensional line plot (cyan solid line) of (x, y, z) in the bottom pane. Label the axes for both plots.
