| sin | sine function (radians) |
| Syntax | sin ( r : real ) : real
|
| Description | The sin function is used to find the sine of an angle given in radians. For example, sin (0) is 0.
|
| Example | This program prints out the sine of p/6, 2p/6, 3p/6, up to 12p/6 radians.
const pi := 3.14159
for i : 1 .. 12
const angle := i * pi / 6
put "Sin of ", angle, " is ", sin ( angle )
end for
