Why removing noise increases my audio file size? In this section we illustrate just a few of the many applications of calculus to business and economics. In economics, calculus allows for the determination of maximal profit by providing a way to easily calculate both marginal cost and marginal revenue. The revenue function is the product of price times quantity sold so $R(q)=(1000-q)q$ since $p=1000-q$. Link to worksheets used in this section. In this context, differential calculus also helps solve problems of finding maximum profit or minimum cost etc., while integral calculus is used to find the cost function when the marginal cost is given and to find total ⦠And the process of finding the anti-derivatives is known as anti-differentiation or integration. Economic research often uses calculus to examine functional relationships. The optimal quantity is hopefully $q=499$. The cost function is easy to determine: $C(q)=2q$. In economics, the idea of marginal cost can be nicely captured with the derivative. If we know the fâ of a function which is differentiable in its domain, we can then calculate f. In differential calculus, we used to call fâ, the derivative of the function f. Here, in integral calculus, we call f as the anti-derivative or primitive of the function fâ. Applications of the Derivative identifies was that this concept is used in everyday life such as determining concavity, curve sketching and optimization.
