Compare The Very Basics of Tensors by Nils K Oeijord, Paperback | Indigo Chapters

Tensor calculus is a generalization of vector calculus, and comes near of being a universal language in physics. Physical laws must be independent of any particular coordinate system used in describing them. This requirement leads to tensor calculus. The only prerequisites for reading this book are a familiarity with calculus (including vector calculus) and linear algebra, and some knowledge of differential equations. | The Very Basics of Tensors by Nils K Oeijord, Paperback | Indigo Chapters
