function Sin (x: Real): Real; |
function Sin (z: Complex): Complex; |
`Sin' returns the sine of the argument. The result is in the range `-1 <= Sin (x) <= 1' for real arguments.
The function `Sin' is defined in ISO-7185 Pascal; its application to complex values is defined in ISO-10206 Extended Pascal.
program SinDemo; begin WriteLn (Sin (SqRt (2) / 2) : 0 : 5) { yields 0.5 since Sin (SqRt (2) /2) = 0.5 } end. |
