Undergrad Eliminating the Parameter from Helix Equation

Click For Summary
The discussion focuses on eliminating the parameter t from the parametric equation of a helix defined as r(t) = <sin(t), cos(t), t>. Participants explore the possibility of expressing the helix in terms of x, y, and z coordinates. The equation for z is expressed as z = t, while x and y are defined as x = sin(t) and y = cos(t). The challenge lies in finding a relationship that connects x and y directly to z without the parameter t. Ultimately, the conversation seeks a way to represent the helix purely in Cartesian coordinates.

Let's say you have a helix defined parametrically as
r(t) =<sin(t), cos(t), t>

Is it possible to eliminate t and write an equation for this helix just in terms of x, y, and z?

How would you express ##z## as a function of ##t##?
##z=## ?
 
x=sin(z), y=cos(z).

Thank you!
