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)
The angle can be a single value or any complex array of values.
- DCOTAN returns the double-precision real cotangent of its double-precision real argument.
- DCOTAN returns NaN if n is not real
Lets see an example in (Column2Row1)
Returns 1.91754 for DCOTAN(40)
Consider another example in (Column2Row2)
Returns NaN for DCOTAN("abc")
| Column1 | Column2 | Column3 | Column4 | |
| Row1 | 40 | 1.191754 | ||
| Row2 | abc | NaN | ||
| Row3 | ||||
| Row4 | ||||
| Row5 | ||||
| Row6 |
