The key point to take from these examples is that an accumulation function is increasing precisely when is positive and is decreasing precisely when is negative. The two main concepts of calculus are integration and di erentiation. Neither of these solutions will satisfy either of the two sets of initial conditions given in the theorem. It just says that the rate of change of the area under the curve up to a point x, equals the height of the area at that point. The Fundamental Theorem of Calculus formalizes this connection. Optimization Problems for Calculus 1 with detailed solutions. While the two might seem to be unrelated to each other, as one arose from the tangent problem and the other arose from the area problem, we will see that the fundamental theorem of calculus does indeed create a link between the two. Explanation: . Fundamental Theorem of Calculus Part 1: Integrals and Antiderivatives. The fundamental theorem of calculus establishes the relationship between the derivative and the integral.
