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 cosine of each of the angles.

SELECT id, angle, COS(angle)
FROM scott.angle

SELECT id, angle, COS(angle)
FROM angle
