[[Manuals/calci/COTAN| COTAN]] can be used if the angle is in Radians.<br/>

The angle can be a single value or any complex array of values.<br/>

For example DCOTAN(1..100) can give an array of the results, which is the COTAN value for each of the elements in the array. The array could be of any values either '+' or '-' like 1..5@DCOTAN or (-5)..(-1)@DCOTAN.

DCOTAN(Number)


  • Number is the angle in Degrees.
    • DCOTAN(),returns the double-precision cotangent of the given angle.

COTAN can be used if the angle is in Radians.
The angle can be a single value or any complex array of values.
For example DCOTAN(1..100) can give an array of the results, which is the COTAN value for each of the elements in the array. The array could be of any values either '+' or '-' like 1..5@DCOTAN or (-5)..(-1)@DCOTAN.

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 'x' is not real

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

  • Type =1..10@DCOTAN in Calci
  • Type =1..10@DCOTAN or 1..10@DCOTAN in ZOS
Angles DCOTAN
1 0.642092616
2 -0.457657554
3 -7.015252551
4 0.863691154
5 -0.295812916
6 -3.436353004
7 1.147515422
8 -0.147065064
9 -2.210845411
10 1.542351045

Examples

DCOTAN(x)

  • x   is the angle in degrees.
  • COTAN(-x)=-COTAN(x)
  • Result shows COTAN(abc)= NAN
DCOTAN(Degrees) Value
DCOTAN (100) -0.1762698070846492
DCOTAN (20) 2.7474774194546225
DCOTAN (-20) -2.7474774194546225
