Documentation/How Tos/Calc: ACOT function

ACOT

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.
