COS
COS(f) returns the cosine of f where f is in radians.
COS(3.14159/3) -> 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);
In this example you return the cosine of each of the angles.
SELECT id FROM angle WHERE func = 'COS'
