Sine
Usage:Sine Angle
 Sin Angle

The Sine command returns the mathematical sine of the entered Angle. Angle is expressed in radians.

In a right triangle the sine is the ratio of opposite leg/hypotenuse.

PI is available as a constant for example, the sine of PI/4 can be computed by Sine PI/4.

To compute the sine of an angle measured in degrees use the function DegToRad which will convert degrees into radians. For example, try Sine DegToRad(90)

Examples:
Sine_1.5708 >d4 returns 1.0000.
Sine_PI/2 returns 1.
Sine_asin(.7) returns .7.
