Description
Based on this page (https://leanprover-community.github.io/undergrad_todo.html), it seems the partial derivative (up to an arbitrary order) is not supported yet in mathlib4.
Can anyone brief the core bottleneck to implement the partial derivative into mathlib4/Lean4? If I want to do this, how challenging it would be?
Thank you!

Research direction
The issue points to the undergrad TODO page and mathlib4/Lean4, but names no file, test, or entry point. Start by reading the linked TODO item and surveying the current calculus support in mathlib4. Done would require a defined approach and API for partial derivatives of arbitrary order, which the issue does not yet specify.
