This is a scripting language developed by Microsoft and is based loosely on Visual Basic. Its functionality in a web environment is dependant upon either an ASP engine or the Windows Scripting Host, and must be used on a Windows hosting platform. 

XAML is a markup language used to define dynamic or static UIs for .NET applications. Though Windows Vista would be used to design XAML UIs, they can be applied to Windows XP or Windows 2003 too.

XAML is similar to MVC in terms of the separation of the UI code from application logic.

XAML is bound to Windows Presentation foundation to build a UI in .NET 3.0 and Windows Vista.

XAML Features:

- XAML inherits all XML definitions and rules.

- It also contains HTML, XHTML and other markup languages for UI.

- Every XAML element represents a .NET CLR class due to which working with XAML becomes simple.

- The application logic can be put in a separate file or be embedded in XAML file itself as XAML in conjunction with Windows Presentation Foundation model to provide the developers design a good UI in ASP.NET.

- XAML files get compiled to BAML files which are smaller than XAML and easier to read which make them faster to load.

Math object has two constant : Math.PI and Math.E

Math object has following functions:

- Math.abs(val1);

It will give absolute value of val1.

- Math.max(val1,val2);

This fuction will return maximum value from val1 and val2.

- Math.random();

This function will return a random number between 0 and 1.

- Math.floor(val1)

This function will returns decimal value of val1

- Class selector can be given to an overall block. This is sometimes termed as block element as well, whereas ID selector identifies a unique name and a style for a specific element.
