{{file:../figures/screenshot_20211216_090917.png}} ## introduction An integral was originally used as an “anti-derivative” in the sense that it was a rigourous way to find the inverse of an derivative ([[differentiation]]). It is made rigourous with [[staircase_function]]s and [[supremum]]s
Choosing the bounds is not something you do wrong or right. It is just something that you do easier or harder.
