Constant of Integration

Definition

The constant of integration is a term that arises in the process of finding the antiderivative or indefinite integral of a function. It represents the unknown value that is added to the result of the integration, ensuring that the final solution satisfies the necessary conditions for the integration process.

1. The constant of integration is denoted by the symbol $C$ and is added to the result of the indefinite integral to represent the family of all antiderivatives of the given function.
2. The constant of integration is necessary to account for the fact that the antiderivative of a function is not unique, as adding a constant to the antiderivative still results in a valid antiderivative.
3. In the context of 3.5 Other Strategies for Integration, the constant of integration plays a crucial role in determining the complete solution when using techniques such as integration by parts, substitution, or trigonometric identities.
4. When solving separable differential equations, as discussed in 4.3 Separable Equations, the constant of integration is essential in finding the general solution, which includes the particular solution and the arbitrary constant.
5. The value of the constant of integration is determined by applying initial conditions or boundary conditions to the problem, which helps to uniquely identify the specific antiderivative or solution.
