ASIN
Returns the inverse sine (the arcsine) of a number.
Syntax:
ASIN(number)
- ASIN returns the inverse trigonometric sine of number, in other words the angle (in radians) whose sine is number. The angle returned is between -PI/2 and +PI/2.
- To return the angle in degrees, use the DEGREES function.
Example:
ASIN(0)
- returns 0.
ASIN(1)
- returns 1.5707963267949 (PI/2 radians).
DEGREES(ASIN(0.5))
- returns 30. The sine of 30 degrees is 0.5.
