Fundamental Theorem of Calculus - Wikipedia - en.wikipedia.org  ## Metadata - Author: **en.wikipedia.org** - Full Title: Fundamental Theorem of Calculus - Wikipedia - Category: #articles - Tags: #calculus #mathematic - URL: https://en.wikipedia.org/wiki/Fundamental_theorem_of_calculus ## Highlights - The fundamental theorem of calculus is a theorem that links the concept of differentiating a function (calculating its slopes, or rate of change at each time) with the concept of integrating a function (calculating the area under its graph, or the cumulative effect of small contributions). The two operations are inverses of each other apart from a constant value which depends on where one starts to compute area.
