why orthogonal parametrization is useful? why is parametrization useful why are orthogonal parametrizations useful why is orthogonal parametrization useful when is parametrization orthogonal why is an orthogonal parametrization useful why are parametrizer parameters useful why orthogonal parametrization is useful why a parametrization is orthogonal parametrization why is orthogonal parametrization useful why is parametrization useful why are parametrizations useful why is parametrization useful which parametrization makes the parameters orthogonal or radial why orthogonal parametrization is useful? why are parametrizations useful why orthogonal parametrization is useful? why is orthogonal parametrization helpful why is orthogonal parametrization useful which is an example of orthogonal parametrization?
