$\text{Notes and tips for the HTML5/JS applets:}$ 

• After selecting the desired applet, a wiki description page appears with a brief description of its contents and user interface. 

• At the top and bottom of this description page, there are links to the actual HTML5 applet.

• The HTML5/JS applets can be rendered by many browsers like Firefox, Chrome and Safari, as well as smartphones and tablets.

• The exercises and the corresponding sample solutions are also integrated into the applet.

$\text{Notes and tips about SWF applets:}$ 

• Our previous SWF applications were programmed for Adobe Flash. 
• Since the Flashplayer browser plugin is no longer supported for security reasons, these applets must be opened with the "projector version". 
• You do not need to install this program and it is not integrated into your browser. There are no security gaps in this respect (as long as you trust the LNTwww).
• On the WIKI pages for the above SWF applets you will find the projector version of the flash player and of course the applet itself. 
• Unfortunately, these applets do not work on smartphones and tablets.
• All SWF applets use the German language.
