SIN
SIN(f) returns the sine of f where f is in radians.
SIN(3.14159/6) -> 0.5
schema:scott
DROP TABLE angle
CREATE TABLE angle( TYPE VARCHAR(10), angle INTEGER id INTEGER INSERT INTO angle VALUES (COS,0,1); INSERT INTO angle VALUES (COS,45,1.732051/2); INSERT INTO angle VALUES (COS,45,1/1.41421); INSERT INTO angle VALUES (COS,60,1/2); INSERT INTO angle VALUES (COS,90,NULL); INSERT INTO angle VALUES (SIN,0,0); INSERT INTO angle VALUES (SIN,30,1/2); INSERT INTO angle VALUES (SIN,45,1/1.41421); INSERT INTO angle VALUES (SIN,60,1.732051/2); INSERT INTO angle VALUES (SIN,90,1); INSERT INTO angle VALUES (TAN,0,0); INSERT INTO angle VALUES (TAN,30,1/1.732051); INSERT INTO angle VALUES (TAN,45,1); INSERT INTO angle VALUES (TAN,60,1.732051); INSERT INTO angle VALUES (TAN,90,1/0);
In this example you return the sine of each of the angles.
SELECT id FROM angle WHERE TYPE = 'SIN'
