The Math object is used to perform mathematical calculations on numbers. Math object is not a constructor. So all the properties and methods of Math are static and can be called by using 'Math' as an object.
Syntax:
var sine_value = Math.sin(45);

Properties of Math Object

Property	Description
Math.E	It returns Euler's number
Math.PI	It returns PI value
Math.SQRT2	It returns the square root of 2
Math.SQRT1_2	It returns the square root of 1/2
Math.LN2	It returns the natural logarithm of 2
Math.LN10	It returns the natural logarithm of 10
Math.LOG2E	It returns base 2 logarithm of E

Methods of Math Object

Method	Description
abs()	It returns the absolute value of a number.
acos()	It returns the arccosine (in radians) of a number.
asin()	It returns the arcsine (in radians) of a number.
atan()	It returns the arctangent (in radians) of a number.
atan2()	It returns the arctangent of the quotient of its arguments.
ceil()	It returns the smallest integer, greater than or equal to a number.
cos()	It returns the cosine of a number.
