Deriving The Product Rule from Symmetry and Units

👉(f⋅g)' ≠ f'⋅g' (inconsistent units)
👉Simplest expression with correct units: f'g or g'f
👉The LHS has a "swapping" symmetry f ⇔ g, hence so must the RHS.
👉Therefore we must 𝒂𝒅𝒅 them https://t.co/3HtCOtVMHA (https://twitter.com/InertialObservr/status/1143600299942113280?s=20)
