SIN

SIN(f) returns the sine of f where f is in radians.

  SIN(3.14159/6) -> 0.5

schema:scott

 DROP TABLE angle

 CREATE TABLE angle(
  id INTEGER,
  angle FLOAT);
INSERT INTO angle VALUES (0,1);
INSERT INTO angle VALUES (1,0.7853);
INSERT INTO angle VALUES (2,0.5235);
INSERT INTO angle VALUES (3,1.0471);

In this example you return the sine of each of the angles.

SELECT id, angle, SIN(angle)
FROM angle
