Send chats : you just have to enter the text in the dedicated input field and then to validate it by pushing the return key ou by clicking on the OK button.
Format the chats :
once you un-collapse the chatbox formatting toolbar by clicking on the BBCode button, you have access to different formatting options for your chats. You can format a chat by selecting a part (or the totality) of it and then select one of the buttons/list. You can also add empty formatting tags by selecting nothing and clicking one of the buttons/menu thus allowing you to add the chat text afterwards between these tags.*
Access to the different channels : you can have access to different channels restricted to only some usergroupds or for specifics use of the chatbox. The different channels are accessible from the buttons on the left of the chatbox.*
Edit your chats (or others chats) : the edition of a chat can be done by a simple double-click on it.*
Use specific commands : some commands can be accessible in the chatbox depending on the will of the administrator(s) of your forum. These commands let you execute specific actions of formatting, management, etc... You will herebelow the information on the command which are accessible to you. You must notice that you are not forced to use the command prefixes (/command_name) when you use them in the channel they are attached to (except in the general channel).*
* : Depending on the settings chosen by the administrator(s) of the forum, you might not have access to all these features.
There is no limit. As you have said the cosine function continually moves between -1 and 1. This means that it does not get continually closer to some fixed value which is the definition of a limit.

The sense of limits approaching infinity in periodic functions
i need help with a question:
the minute hand on a watch is 8mm long and the hour hand is 4mm long. how fast it the distance between the tips of the hands changing at 1 oclock? Thanks !
Well, first look at what's put inside the cosine function. As x approaches infinity when you have 1/x, that's 1 being divided by VERY large numbers which we can thus conclude is equivalent to 0. Taking the cos(0) you'll get 1.
So now we have 1^(x^2) as x approaches infinity, but the (x^2) is now kinda useless at this point; 1 raised to any power is 1.
