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 'x' 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@DCOTAN or 1..10@DCOTAN in ZOS
Number 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 radians.
  • COTAN(-X)=-COTAN(X)
  • Result shows COTAN(abc)= NAN
DCOTAN(Radian) Value
DCOTAN (100) 0.1762698070846492
DCOTAN (20) 2.7474774194546225
DCOTAN (-20) 2.7474774194546225

DTAN(n)

where

is the angle in radian.


DTAN returns the double-precision real tangent of its double-precision real argument.


DTAN returns NaN if n is not real


DTAN


Lets see an example in (Column2Row1)

=DTAN(Column1Row1)

Returns 0.8391 for DTAN(40)

Consider another example in (Column2Row2)

=DTAN(Column1Row2)

Returns NaN for DTAN("abc")
