I found math in physics to have this really fun duality of “these are rigorous rules that must be followed” and “if we make a set of edge case assumptions, we can fit the square peg in the round hole”
Also I will always treat the derivative operator as a fraction

Mathematicians will in one breath tell you in one breath tell you they aren’t fractions, then in the next tell you dz/dx = dz/dy * dy/dx

Have you seen a mathematician claim that? Because there’s entire algebra they created just so it becomes a fraction.

Brah, chain rule & function composition.

This is until you do multivariate functions. Then you get for f(x(t), y(t)) this: df/dt = df/dx * dx/dt + df/dy * dy/dt

(d/dx)(x) = 1 = dx/dx

Not very good mathematicians if they tell you they aren’t fractions.
