Trigonometric functions
Trigonometric functions are used to calculate degrees, angles, and other geometric data.
Note All trigonometric functions use radians as the unit of measure. Once you have a result, you
can convert the radians into degrees using the
Degrees function.

Acos
Purpose
Returns the arccosine (Acos), or inverse cosine, of number.
Format
Acos (number)
Parameters
number - any numeric expression or field containing a numeric expression in the range -1 to 1
Data type returned
number
Originated in
FileMaker Pro 9.0
Description
The arccosine is the angle whose cosine is number. The returned angle is given in radians in the
range 0 (zero) to Pi. The input number parameter must be between -1 and 1.
If you want to convert the result from radians to degrees, multiply it by 180/Pi or use the Degrees
function.
This function Returns
Acos The arccosine, or inverse cosine, of a number.
Asin The arcsine, or inverse sine, of a number.
Atan The trigonometric arc tangent, or inverse tangent, of a number.
Cos The cosine of the specified angle.
Degrees Degrees, converted from the specified radians.
Pi The value of the constant Pi, which is approximately 3.14159.
Radians Radians, converted from the specified degrees.
