I'm a math professor, and I'd like to use your graphic of the transformation from cube to parallelepiped in my linear algebra class to talk to my students about the significance of the determinant. Would that be ok with you? It is a really great graphic!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3596550435682943926.post-9626722563071742022021-10-08T09:26:00.321-07:002021-10-08T09:26:00.321-07:00Calculator: scale matrix.
