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@DCOTAN or 1..10@DCOTAN in ZOS
