Final answer:
Don't forget about the constant of integration when doing an indefinite integral.
Step-by-step explanation:
When doing an indefinite integral, don't forget about the constant of integration. The constant of integration, usually denoted as C, is added at the end of the integration process and represents the family of all possible solutions to the integral. It arises because when we integrate a function, there are infinitely many antiderivatives.
For example, when integrating the function f(x) = 2x, the indefinite integral is F(x) = x^2 + C, where C is the constant of integration.
Remember to always include the constant of integration when finding the solution to an indefinite integral.
