Suppose I have the following transformation:
[tex]
u = \frac{x}{x^2+y^2+z^2}
[/tex]
[tex]
v = \frac{y}{x^2+y^2+z^2}
[/tex]
[tex]
w = \frac{z}{x^2+y^2+z^2}
[/tex]
Is there a fast way to calculate the determinant jacobian without having to deal with the whole 3x3 determinant?
I noticed that the inverse transformation is the same (switching x,y,z with u,v,w gives the equality again) but the determinant is not 1, so I don't really know if this can help.
Or would I really have to do it the long and boring way?
