There is a nice book named "The Calculus Wars" by
@JasonBardi that discusses how Newton and Leibniz came up with different notations for derivatives and integrals, and how Leibniz's notation was widely adopted and survives to this day. Leibniz also introduced ∫ for integrals.Thanks. Twitter will use this to make your timeline better. UndoUndo

It looks like d²x/dy² to me. Did Leibniz usually have his axes the other way around from modern tradition?

Newton started with d^2y/dx^2 so maybe we have been using the 'Newtonian' way.

So to put in the perspective of the covid19, dy2/dt2 is the rate of daily new cases. If daily new cases is still increasing, dy2/dt2 is positive, otherwise is negative. The point at which dy2/dt2 goes from positive to negative is the ‘inflection point’.

As an English major I am impressed with this. I have no idea what it represents. But I am impressed. Meanwhile the need to use Algebra 2 content in my daily life grows smaller every day. Now back to diagramming sentences.

What about stem. They are very good fields and the level of calculus required is not changing.
