DTAN(x)


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

TAN 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 COT function i.e.,Tan(x) = 1 / COT(x) or SIN(x) / COS(x).
  • In a right angled triangle Tan(x) = Opposite side / Adjacent side.
  • To obtain the value in Radians multiply with PI()/180 or use Tan function TAN(X)
  • DTAN 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 DTAN is applied to an array of numbers containing numbers 1..10.

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

DTAN(x)

  • x   is the angle in radians.
  • COTAN(-X)=TAN(X)
  • Result shows TAN(abc)= NAN
DTAN(Radian) Value
DTAN (100) 0.1762698070846492
DTAN (20) 2.7474774194546225
DTAN (-20) 2.7474774194546225
