I’ve worked through a computation-heavy, “standard” but quite nonrigorous treatment of multivariable calculus in the past. What book would do well as a rigorous (but not overly) “second course”? In particular, I’m looking for a book that
treats differential forms
treats the inverse and implicit function theorems
and leads well into an intro manifolds book like Tu’s one. (Bonus points if it actually talks a bit about manifolds itself or works with differential forms defined on manifolds instead of only $\Bbb R^n$!)
Possible recommendations – I’m not 100% sure if what you are looking for exists but these are all well-written and worth investigating.
The last one is particularly nice, in my opinion.
