Visual calculation
Returns the arcsine, or inverse sine, of a number. The arcsine is the angle whose sine is number. The returned angle is given in radians in the range -pi/2 to pi/2.
Syntax
ASIN(number)
Parameters
| Term | Definition |
|---|---|
number |
The sine of the angle you want and must be from -1 to 1. |
Return value
Returns the arcsine, or inverse sine, of a number.
Remarks
To express the arcsine in degrees, multiply the result by 180/PI( ) or use the DEGREES function.
Example
| Formula | Description | Result |
|---|---|---|
= ASIN(-0.5) |
Arcsine of -0.5 in radians, -pi/6 | -0.523598776 |
= ASIN(-0.5)*180/PI() |
Arcsine of -0.5 in degrees | -30 |
= DEGREES(ASIN(-0.5)) |
Arcsine of -0.5 in degrees | -30 |
