so, |r| = a do you understand that?

Substitution is trivial.

I get that part but what do you mean by trivial?

trivial means it is too simple from here to bother writing out, also how are you my friend momentazeus you should sing us a song

How can you says that the vector notation of the sphere uses the same r given for the vector intersecting the sphere?

The sphere is not written in vector notation in fact there is no equation of sphere. "a" is the radius in this context which is some constant like 5.

|r| is the distance from the origin. The definition of |r| is as follows, (r dot_product r)^1/2.
