Find the average value of a function over a closed interval. - The integral has a variable as an upper limit rather than a constant. Using the Fundamental Theorem of Calculus, evaluate this definite integral. Once again, we will apply part 1 of the Fundamental Theorem of Calculus. This will show us how we compute definite integrals without using (the often very unpleasant) definition. $$This can be proved directly from the definition of the integral, that is, using the limits of sums. Since denotes the anti-derivative, we have to evaluate the anti-derivative at the two limits of integration, 0 and 3. 5 0 obj The Fundamental Theorem of Calculus, Part 1 [15 min.] These do form a fundamental set of solutions as we can easily verify. Thus, the two parts of the fundamental theorem of calculus say that differentiation and integration are inverse processes.
