To determine around which axis the profile curve was revolved, let’s rearrange the given equation:
This form suggests that for a fixed value of
(where
can be between positive and negative values), the equation describes a circle in the
-plane. This indicates that the profile curve representing
and
must have been revolved around the
-axis to generate the surface of revolution.
Now, in the
-plane, by letting
, the profile curve is given as:
Taking the positive and negative roots, we get:
Thus, the equation of the profile curve in the
-plane is
