DCOTAN(x)


  • where x is the angle in Radians
  • by default Calci use Radian as angle

COTAN can be used if the angle is in Radians.

Description

  • This function is used to obtain the Cotangent value of 'x' in degrees.
  • It is the reciprocal of TAN function i.e.,Cotan(x)=1/Tan(x) or Cos(x)/Sin(x).
  • In a right angled triangle Cotan(x) = Adjacent side / Opposite side.
  • To obtain the value in Radians multiply with PI()/180 or use Cotan function COTAN(X)
  • DCOTAN returns NaN if n is not real

The angle can be a single value or any complex array of values.

The following example shows how COTAN is applied to an array of numbers containing numbers 1..10.

  • Type =1..10@DCOTAN in Calci
  • Type =1..10@SIN or 1..10@DCOTAN in ZOS
