| | | The arccosine of an angle is the inverse of the COS function. |
| | | The "number" is the cosine of an angle in radians. |
| | | If "number" is not numeric, then #VALUE! is returned. |
| | | The returned angle is given in radians between 0 and PI. |
| | | If your argument is in degrees, multiply it by PI/180 to convert it to radians. |
| | | If you want to convert the result from radians to degrees, multiply it by 180/PI. |
| | | You can use the DEGREES function to convert from radians to degrees. |
