I am repeting some multivariable calculus.(adsbygoogle = window.adsbygoogle || []).push({});

I want to know if have done right now:

[tex]\mathbf{r} = \mathbf{r}(q_1, q_2, q_3)[/tex]

[tex] \dfrac{\partial \mathbf{r}}{\partial q_1} = \left(\dfrac{\partial r_1}{\partial q_1} , \dfrac{\partial r_2}{\partial q_1} , \dfrac{\partial r_3}{\partial q_1} \right) [/tex]

let

[tex] \mathbf{r} = (q_1 + 2q_3, q_2 + 3q_1 - q_3, q_1 - q_3) [/tex]

[tex] \dfrac{\partial \mathbf{r}}{\partial q_1} = (1,3,1) [/tex]
