Where does integral concept come from?

$begingroup$
I have been searching for days to find why Newton offered an anti-derivative function to find the area under the curve. What was the reason for searching such a function? Was it just mathematical curiosity or was there a solid reason for that?

I would say the theory of integration in Newton's time was a development beyond the quadrature technique known to the ancient Greeks. His achievement -- with the concept of a derivative already understood -- was to observe that the area $A(x)$ under the "curve" $y = f(x)$ above the segment $[a,x]$ had the property $frac{dA}{dx}(x) = f(x)$. I don't know the precise "reason for searching" but it is clear that Newton was exceptional in terms of scientific observation.

Historically when searching for the area $A(f(x),[0,t])$ under $f(x)=x^n,x in [0,t]$ or $f(x)=frac{1}{1+x}$ it is natural to search how $A(f(x),[0,t])$ transforms under $t mapsto t+1$ or $t mapsto 2t$. When those transformations are fully understood they give an explicit formula for the area.

Newton was not the first mathematician to do so. Go back in the history, Cavalieri, Torricelli, and before ...
