Calculate the Height of Christmas

Someone I know said that Christmas is on the horizon. If that is the case we should be able to calculate its height given that we are on a curved sphere of known circumference and know the pace at which Christmas is approaching. Given the earth's…

Curvature and torsion of a helix

I would like to calculate the curvature and torsion for a helix knowing the radius $r$, pitch $2pπ$, center $s$, and direction axis $d$. Can anyone help? I know how to compute curvature and torsion for $H = r\cos(t),\space r\sin(t),\space z$. Thank…
