In somewhere in wikipedia, I found a "shortcut" for compute the jacobian, the formula is: \frac{\partial(q_1 , q_2 , q_3)}{\partial (x, y, z)} = h_1 h_2 h_3 where q represents the coordinate of other system and h its factor of scale.

I know that this relationship is true. What I'd like of know is if this equation below is true: \frac{\partial(q_1 , q_2 , q_3)}{\partial (Q_1, Q_2, Q_3)} = \frac{h_1 h_2 h_3}{H_1 H_2 H_3} where Q represents the coordinate of another system and H its factor of scale.

Is correct to affirm that the jacobian is equal to the quotient between the scale factors?

What you did is to invent a definition of \frac{\partial(q_1 , q_2 , q_3)}{\partial (Q_1, Q_2, Q_3)} . It is not true nor false: it is a definition.
 
Thread 'Derivation of equations of stress tensor transformation'
Hello ! I derived equations of stress tensor 2D transformation. Some details: I have plane ABCD in two cases (see top on the pic) and I know tensor components for case 1 only. Only plane ABCD rotate in two cases (top of the picture) but not coordinate system. Coordinate system rotates only on the bottom of picture. I want to obtain expression that connects tensor for case 1 and tensor for case 2. My attempt: Are these equations correct? Is there more easier expression for stress tensor...
