The SECOND function extracts the seconds from a date.

SECOND(datetime)

Â date-time: Any valid Numbers date or time value.

SIGN

The SIGN function returns 1 when the argument number is positive, –1 when it is

negative, and 0 when it is zero.

Â number: The number you want to find the sign of. It can be a reference to a cell

containing a number.

SIN

The SIN function calculates the sine of an angle in radians.

SIN(radian-angle)

Â radian-angle: The angle in radians.

Notes

If you measure angles in degrees instead of radians, you can use the RADIANS function

If you want to express radians as a multiple of pi, you can use the PI() function to

provide a value for pi.
