TAN
TAN(f) returns the tangent of f where f is in radians.
TAN(3.14159/4) -> 1
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 tangent of each of the angles.
SELECT id, angle, TAN(angle) FROM angle
