- ASIN (Arc Sine)
- Calculates the arc sine, or inverse, of a sine. The result is the corresponding angle in radians, in the range -PI/2 to PI/2.
-
- Format: ASIN (number)
-
- Argument:
- ΓÇó number: A sine value or a simple operation that yields a sine. Valid range is -1.0 to 1.0.
-
- Example:
- ASIN (1) returns 1.570.
- Shows that the arc sine of 1 is PI/2 radians (1.57), which is 90 degrees.
