DCOTAN(x)
- where x is the angle in Radians
- by default Calci use Radian as angle
COT can be used if the angle is in Radians.
Description
This function gives the cotangent value of 'x' in degrees.
This function 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.
This function used to display the answer in degrees.
To convert that in to 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 |
