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 angle
