- Which functions can I plot here?
- Are there any pre-defined constants?
- Can I add more than one graph to my plot?
- Can I save my graphs to a file?
- How can I define the x-range I want to plot?
- Why can I not download my graphs?

A polynomic function you can enter like this:

A gaussian distribution with standard deviation 2 looks like this:

The following functions are already pre-defined:

`sin` | sine function |

`cos` | cosine function |

`tan` | tangens function |

`asin` | arcus sine function |

`acos` | arcus cosine function |

`atan` | arcus tangens function |

`sinh` | hyperbolic sine function |

`cosh` | hyperbolic cosine |

`tanh` | hyperbolic tangens function |

`asinh` | hyperbolic arcus sine function |

`acosh` | hyperbolic arcus tangens function |

`atanh` | hyperbolic arcur tangens function |

`log2` | logarithm to the base 2 |

`log10` | logarithm to the base 10 |

`log` | logarithm to the base 10 |

`ln` | logarithm to base e (2.71828...) |

`exp` | e raised to the power of x |

`sqrt` | square root of a value |

`sign` | sign function -1 if x<0; 1 if x>0 |

`rint` | round to nearest integer |

`abs` | absolute value |

The input can be done using our WYSWYG formula editor. Therefore you do not have to care about correct syntax.

`pi` | 3.1415... |

`e` | 2.7182... |
