Any real number or a reference to a cell containing a number |
Examples of use
Calculation of arccotangent for 1
=ACOT(1)
Result: approximately 0.7854 radians (or 45°).
Calculation for a negative number
=ACOT(-1)
Result: approximately -0.7854 radians (−45°).
Calculation for zero
=ACOT(0)
Result: π/2 radians (~1.5708), since the arccotangent of zero is π/2.
Notes
The value returned by the function is in radians in the range from 0 to π.
