...system, I mean as in the Cartesian Vector/Tensor definition.(adsbygoogle = window.adsbygoogle || []).push({});

I get that if you have two mutually orthogonal basises which are theta degrees apart and the transformation from one basis to the other follows the same as a rotation by theta degrees i.e:

V^{'}_{i}= R_{ij}V_{j}

then it is a Cartesian vector.

Does that mean if you wanted to change the basis from a mutually orthogonal one to a non mutually orthogonal oneVwould no longer be a Cartesian vector? Are there any other (better) examples of non Cartesian Vectors?

Thanks
