Screw Motion

need to describe the motion of a point on a screw or a helix without using polar coordinates, preferred simple math using different. and integration (rotating?) terms?
RPF responses thank you!

x = r cos (t), y = r sin (t), z = pt/2pi

r =
t = time (in arbitrary units such that the rate of one round is 2Pi)
p =

Couple!
