      How do I "define" a semi-circle by an equation when Y is linear?


      I know the cartesian formula:

      x = 4 * cos ( t * 180 )

      y = 4 * sin ( t * 180 )

      z = 0


      But I need to compensate for the trajectory (Y) which has a linear value.

      I need the formula applied only to X given Y is linear 0-1.


      I want to sweep a VSS to make this shape. The trajpar is the given value (t as Y):
