Are there more books like Div, Grad, Curl and all that by HM Schey?
It's hard to describe by what I mean by "books like" to someone who hasn't read above mentioned text, but roughly it means teaching the subject from a less rigorous point of view as a first introduction. Being a physics major these books are perfect for me at the level I am currently studying, having said that there are plenty of books that try to do the same but makes it even harder to understand than a proper math text, the likes of which are almost all math methods book for physicists.
Another good point of Schey's book is that it introduces the subject from a physical point of view in a justifiable manner without requiring the understanding of physics discussed in the book beforehand, unlike for example Sadri Hassani's math methods.
The only other book that I find of such manner was Calculus Made Easy by Silvanus P. Thompson.
I don't have any particular topic on which I want recommendations, it could be any topic at any level.
