Returns the inverse cotangent (the arccotangent) of a number.
Syntax:
ACOT(number)
returns the inverse trigonometric cotangent of number, in other words the angle (in radians) whose cotangent is number. The angle returned is between 0 and PI.To return the angle in degrees, use the DEGREES function.
Example:
ACOT(1)
returns 0.785398163397448 (PI/4 radians).
DEGREES(ACOT(1))
returns 45. The tangent of 45 degrees is 1.
