Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I have encountered an exercise in my differential geometry book: to derive the parametrisation and the cartesian equation of the curvewitch of Agnesi.

To see how it is constructed please see:

How would one derive the results? I am lost. Please help. Thanks.
