It generated a whole new branch of mathematics used to torture calculus 2 students for generations to come – Trig Substitution. Recall that the The Fundamental Theorem of Calculus Part 1 essentially tells us that integration and differentiation are "inverse" operations. For now lets see an example of FTC Part 2 in action. Now that we know k, we can solve the equation that will tell us the time at which Lou started painting the last 100 square feet: Rearranging, we get a (horrible) quadratic equation: We saw the computation of antiderivatives previously is the same process as integration; thus we know that differentiation and integration are inverse processes. . This is not in the form where second fundamental theorem of calculus can be applied because of the x 2. Using calculus, astronomers could finally determine distances in space and map planetary orbits. Three Different Concepts As the name implies, the Fundamental Theorem of Calculus (FTC) is among the biggest ideas of calculus, tying together derivatives and integrals. We need an antiderivative of \(f(x)=4x-x^2\). Here, the "x" appears on both limits. Solution: The net area bounded by on the interval [2, 5] is ³ c 5 If g is a function such that g(2) = 10 and g(5) = 14, then what is the net area bounded by gc on the interval [2, 5]?
