Insights The Pantheon of Derivatives - Important Theorems (V)

[fresh_42]

The final part of our visit to the Pantheon of Derivatives lists the most important theorems (my biase, of course) in the realm of derivatives: from the Implicit Function to Noether's Theorem.

1) regarding the Implicit Function Theorem:
there is no need to demand $f$ to be totally differentiable in $(x,y)$ Actually $f$ must be differentiable just in the second argument while the first one can belong to a topological space. By the way, $\mathbb{R}^m$ can also be replaced with a Banach space.

2) Formula (15) holds for any Riemann manifold and follows from (14) with the help of results from previous part.

I think that theCauchy-Goursat Theorem can also be obtained from the Stokes formula without a considerable loss of generality.
