The Fundamental Theory of Calculus part 2 (part ii)
OK, get ready for some Calculus-Fu! We have now said that rather than taking pesky limits of Riemann sums to calculate areas under curves (ie. definite integrals), all we need is to find an antiderivative of the function that we are looking at. As a reminder, to calculate the definite integral of a continuous function, we have: $latex
