acot

Inverse cotangent

Syntax

• Y = acot(X)
  

Description

Y = acot(X) returns the inverse cotangent (arccotangent) for each element of X.

The acot function operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians.

Examples

Graph the inverse cotangent over the domains and .

• x1 = -2*pi:pi/30:-0.1;
  x2 = 0.1:pi/30:2*pi;
  plot(x1,acot(x1),x2,acot(x2)), grid on
  
  
  

Definition

The inverse cotangent can be defined as

Algorithm

acot uses FDLIBM, which was developed at SunSoft, a Sun Microsystems, Inc. business, by Kwok C. Ng, and others. For information about FDLIBM, see http://www.netlib.org.
