Math.LOG2E:	The number value for the base-2 logarithm of e, the base of the natural logarithms; this value is approximately 1.4426950408889634.
Math.LOG10E:	The number value for the base-10 logarithm of e, the base of the natural logarithms; this value is approximately 0.4342944819032518.
Math.PI:	The number value for Π (pi), the ratio of the circumference of a circle to its diameter, which is approximately 3.1415926535897932.
Math.SQRT1_2:	The number value for the square root of 1/2, which is approximately 0.7071067811865476.
Math.SQRT2:	The number value for the square root of 2, which is approximately 1.4142135623730951.

Syntax:	Math.acos(x)
	Returns an implementation-dependent approximation to the arc cosine of x. The result is expressed in radians and ranges from +0 to +π(pi). The argument must be between -1 and 1.
Return value:	A number or NaN for x > 1 and x < -1.
An example of using the Math.acos() :

Syntax:	Math.asin(x)
	Returns an implementation-dependent approximation to the arc sine of x. The result is expressed in radians and ranges from -π/2 to +π/2. (-pi/2 to pi/2) The argument must be between -1 and 1.
Return value:	A number or NaN for x > 1 and x < -1.
An example of using the Math.asin() :

Syntax:	Math.atan(x)
	Returns an implementation-dependent approximation to the arc tangent of x. The argument can be any number between -∞ to +∞
Return value:	A number expressed in radians and ranges from -π/2 to +π/2.(-pi/2 to pi/2)
An example of using the Math.atan() :

Syntax:	Math.atan2(y, x)
	Returns an implementation-dependent approximation to the arc tangent of the quotient y/x of the arguments y and x, where the signs of y and x are used to determine the quadrant of the result. Note that it is intentional and traditional for the two-argument arc tangent function that the argument named y be first and the argument named x be second.
Return value:	A number expressed in radians and ranges from ?π to +π.
An example of using the Math.atan2() :

Syntax:	Math.ceil(x)
	Rounds a floating-point value, x, up to the closest integer. If x is already an integer, the result is x.
Return value:	A integer number.
An example of using the Math.ceil() :

Syntax:	Math.cos(x)
	Returns an implementation-dependent approximation to the cosine of x. The argument is expressed in radians. To convert degrees to radians, multiply the degree value by 2π/360. (2*pi/360)
Return value:	A number between -1.0 and 1.0.
An example of using the Math.cos() :

Syntax:	Math.exp(x)
	Returns an implementation-dependent approximation to the exponential function of x. e raised to the power of x, where e is the base of the natural logarithms. (e^x)
Return value:	A number.
An example of using the Math.exp() :

Syntax:	Math.floor(x)

Syntax:	Math.random()
	Generate a number randomly or pseudo randomly with approximately uniform distribution over a range ( >=0 and <1), using an implementation-dependent algorithm or strategy.
Return value:	A number between >=0 and <1
An example of using the Math.random() :

Syntax:	Math.round(x)
	Rounds its argument, x, up or down to the nearest integer. For example, it rounds 4.5 to 5 and rounds -4.5 to -4. If x is already an integer, the result is x.
