Chapter 5: Integration Module 5.1. Antiderivetive – The indefinite integral
1. Antiderivative
- Antiderivative: A function F(x) for which for
every x in the domain of f is said to be an antiderivative of
f(x).
'( ) ( )F x f x
- Fundamental Property of Antiderivative: If F(x) is an antiderivative of the continuous function f(x), then any other antiderivative of f(x) has the form
G(x) = F(x) + C , for some constant C.

1. Antiderivative
We will represent the family of all antiderivatives of f(x) by using the symbolism:
which is called the indefinite integral of f

3. Practical applications
Example 1: It is estimated that x months from now the polulation of a certain town will be changing at the rate of
people per month. The current population is 5000. What will be the population 9 months from now ? 4 6 x
Example 2: A manufacturer has found that marginal cost is dollars per unit when q units have produced.The total cost of producing the first 2 units is $ 900. What is the total cost of producing the first 5 units ?
23 5 100q q
