<![CDATA[
function Sin ( const Number : Extended ) : Extended;
Description
The Sin function is a mathematical function giving the Sine value of a Number value given radians.
PI radians = 180 degrees
Notes
The System unit supports only the following angular functions:
ArcTan
Sin
Cos
Related commands
ArcCos The Arc Cosine of a number, returned in radians
ArcSin The Arc Sine of a number, returned in radians
ArcTan The Arc Tangent of a number, returned in radians
Cos The Cosine of a number
Tan The Tangent of a number
Example code : Get the Sine of 30 degrees
var
float : single;
begin
// The Sine of 30 degrees = 0.5
float := Sin(PI/6); // = 180/6 = 30 degrees
ShowMessage('Sin(PI/6) = '+FloatToStr(float));
end;
