Theorem
Let $\HH$ be a circular helix embedded in Cartesian $3$-space whose axis coincides with the $z$-axis.
$\HH$ can be described by the parametric equation:
- $\begin{cases}
x & = a \cos t \\ y & = a \sin t \\ z & = b t \\ \end{cases}$ where $t$ is the parameter.
Proof
This theorem requires a proof. In particular: It needs to be proved that the tangent to $\HH$ is at a constant angle to the $z$-axis You can help $\mathsf{Pr} \infty \mathsf{fWiki}$ by crafting such a proof.
