I noticed that it dosen't project to the origin of the plane from the north pole. However the projection describes it as mapping to the whole equitorial plane which is wrong!(adsbygoogle = window.adsbygoogle || []).push({});

i.e take S^1 projecting to R.

From the north pole the projection formula is y=-(x-a)/a however a can't be 0. So the origin is never mapped.
