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 tangent of each of the angles.
SELECT id, angle, TAN(angle)
FROM angle
