# Integrale, Summen und Grenzwerte

## Integrale

Ein Integral-Ausdruck kann mit dem hinzugefügt werden `\int_{lower}^{upper}` Befehl zu interpretieren ist.

Beachten Sie, dass der Integral-Ausdruck im Inline- und im Display-Mathemodus etwas unterschiedlich aussehen kann.

## Mehrfachintegrale

Um Doppel-/Dreifach-/Mehrfachintegrale und Umlaufintegrale zu erhalten, müssen Sie `amsmath` und `esint` (für Umlaufintegrale) Pakete.

## Summen und Produkte

Wie beim Integral kann ein Summenausdruck mit dem hinzugefügt werden `\sum_{lower}^{upper}` Befehl zu interpretieren ist.

| LaTeX-Code                                       | Ausgabe                                                                                   |

Auf ähnliche Weise können Sie einen Ausdruck mit dem Produkt einer Folge von Faktoren mithilfe des `\prod_{lower}^{upper}` Befehl zu interpretieren ist.

| LaTeX-Code                               | Ausgabe                                                                                     |

## Grenzwerte

Ein Grenzwert-Ausdruck kann mit dem hinzugefügt werden `\lim_{lower}` Befehl zu interpretieren ist.

| LaTeX-Code                                   | Ausgabe                                                                           |

Dasselbe Produkt in der Anzeige:
\[
    \prod_{i=a}^{b} f(i)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/de/mathematik/09-integrals-sums-and-limits.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
