Synopsis

The SIN trigonometric function returns the sine of the specified angle. The specification for the SIN function is:

FUNCTION SIN (angle NUMBER) RETURN NUMBER;

where angle must be expressed in radians. If your angle is specified in degrees, then you should call SIN as follows:

my_sine := SIN (ACOS(-1)*angle_in_degrees/180);
