Sin

function Sin(const X: Extended): Extended;

The Sin function is a mathematical function giving the Sine value of a number value given radians.

Example

 const
   PI = 3.14;
 
 var
   floatValue : float;
 
 {
 
   floatValue = Sin(PI/6);
   ShowMessage('Sin(PI/6) = '+FloatToStr(floatValue));
 
 }

Output:

Sin(PI/6) = 0,499770102643102
