### Which functions can I plot here?

You can use this tool to plot the graphs of functions depending on one variable. The function variable has to be x!

A polynomic function you can enter like this: 2.5*x^2+3*x-5
A gaussian distribution with standard deviation 2 looks like this: 1/(2*sqrt(2*pi))*exp(-1/2*((x-5)/2)^2)

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.

### At the moment the following constants are pre-defined:

At the moment the following constants are pre-defined:

 `pi` 3.1415... `e` 2.7182...

### Can I add more than one graph to my plot?

For the moment it is not possible to add more than one graph to a plot. However, this feature will be implemented soon.

### Can I add more than one graph to my plot?

If you want to store your plot it is recommended to make a screenshot of the page. It will be possible to export your plots soon. The feature has not yet been implemented.

### How can I define the x-range I want to plot?

Just go to the section "Axis properties" at the bottom of the page to define the x-range for your graph.

### Why can I not download my graphs?

The export feature works only properly with modern browsers. If your download does not work or the plot is exported incompletely we recommend you to take a screenhost instead. You can create a screenshot easily by pressing the "Print" key at your keyboard.

### What file formats can you export the plots?

The standard format which is used to export the plots to is the PDF format. In case you want other formats like Epub (see link for comparision) you could use an online file converter.

Further useful tools: Further useful tools for converting our output PDFs to different file formats are the following ones. Further useful tools for converting our output PDFs to different file formats are the following ones
• DOC to PDF: Converts the DOC to PDF documents
• PDF to Epub Converter. In case you need to convert the PDFs created by this site to Epub Ebooks you can do it with this converter

### I want to merge different PDFs?

We do not offer such a service ourselves. However you can use the following smart online tool to merge your output PDFs. Simply use combine PDF in order combine different PDF files you downloaded here.
