   D(x²) = 2xdx + dx² (ignored)
   (xdx is the area of the small rectangle, 2 coz two rectangles)
   df = 2xdx
   df/dx = 2x

   Oh fuck. He just derived D(t³) = 3t²

   at time t [s(t)] and a small time dt [s(t+dt)]

   Instead of two points

   In pure math, the derivation is not this ratio d(s)/d(t) (t) for a specific choice of dt (=0.001). Instead, it's whatever that ratio approaches, as your choice for dt approaches 0.

   It is equal to the slope of the line tangent to the graph at a *single* point.

   Ese. The difference of distance traveled at time t [s(t)] and a small time dt [s(t+dt)] by change in time d(t).

    the Derivative of the Area (which is Integral) gives the Function. and the Integral of the Function gives the Area.

    Area of circle came from area of triangle. 😲

    Which started from adding circumference (2πr) of smaller circles
