This function calculates the arccosine, that is, the angle whose cosine is the specified value
- Library: PQL \ Spreadsheet \ Math & Trig
- Compatibility: Any content (regardless of data source) in the Tabulate spreadsheet module
- Solve: This function can be used with the Solve plug-in: both as part of the objective function and constraint functions
For the argument, you can specify the cosine of the angle you want to return, which must be a value between –1 and 1
This function is the same as the Microsoft Excel 'ACOS' function - using the same inputs, logic and outputs.
