An antiderivative of a function fx is a function fx such that f0x fx. Note this tells us that gx is an antiderivative for fx. The fundamental theorem of calculus justifies the procedure by computing the difference between the antiderivative at the upper and lower limits of the integration process. First fundamental theorem of calculus ftc 1 if f is continuous and f f, then b. The fundamental theorem of calculus if we refer to a 1 as the area correspondingto regions of the graphof fx abovethe x axis, and a 2 as the total area of regions of the graph under the x axis, then we will. Another proof of part 1 of the fundamental theorem we can now use part ii of the fundamental theorem above to give another proof of part i, which was established in section 6.
