Antiderivatives, Integrals, and Initial Value Problems • Knowing f’, can we determine f ? General and specific solutions: The antiderivative. • The integral symbol: Representing antiderivatives • Initial Value Problems: Transforming a general antiderivative into a specific function that satisfies the given information.

If we know a rate function . . . Carlota Music Company estimates that the marginal cost of manufacturing its Professional Series guitars is given by the following in dollars/month when the level of production is x guitars/month: C'(x) = 0.004x + 50. The fixed costs incurred by Carlota are $9000/month. Determine a model for the total monthly cost C(x) incurred by Carlota in manufacturing x guitars/month. MAT 145
Approximating Area: Riemann Sums To generate a way to calculate the area under the curve of a rate function, in order to determine an accumulation, we begin with AREA APPROXIMATIONS. We create something called a Riemann Sum and use better and better area approximations that will lead to exact area. MAT 145

The Fundamental Theorem of Calculus (Part II) Let f be continuous on [a, b]. Then, where F is any antiderivative of f; that is, F′(x)= f(x). MAT 145
The Fundamental Theorem of Calculus (Part I) For f continuous on [a, b], let the function gbe Then g(x) is an antiderivative of f: MAT 145
