Sin

Returns the sine of an angle.

Synopsis

Sin(number)

Arguments

The number argument can be any valid numeric expression that expresses an angle in radians.

Description

The Sin function takes an angle and returns the ratio of two sides of a right triangle. The ratio is the length of the side opposite the angle divided by the length of the hypotenuse. The result lies in the range -1 to 1.

To convert degrees to radians, multiply degrees by pi/180. To convert radians to degrees, multiply radians by 180/pi.

Examples

The following example uses the Sin function to return the sine of an angle:

Dim MyAngle
MyAngle = 1.3          ' Define angle in radians.
Println Sin(MyAngle)

The following example uses the Sin function to return the cosecant of an angle:

Dim MyAngle, MyCosecant
MyAngle = 1.3                   ' Define angle in radians.
MyCosecant = 1 / Sin(MyAngle)   ' Calculate cosecant.
Println MyCosecant
