Introduction to Integral Calculus
This page introduces the concept of integral calculus and its relationship to differentiation. It explains the fundamental idea of finding antiderivatives, also known as indefinite integrals.
Definition: Integration is the process of calculating integrals, which is the reverse operation of differentiation.
The page illustrates the connection between derivatives and antiderivatives, showing how integrating or"anti−differentiating" a function leads to its antiderivative.
Example: For the function fx = 2x, the antiderivative Fx = x² + C, where C is a constant.
The concept of unbestimmte Integrale indefiniteintegrals is introduced, emphasizing that there are infinitely many antiderivatives for a given function, differing only by a constant.
Highlight: The notation for indefinite integrals is ∫fxdx = Fx + C, where C is an arbitrary constant of integration.
