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@SIN or 1..10@DCOTAN in ZOS
| Number | DCOTAN |

| 1 | 0.642092616 |
| 2 | -0.457657554 |
| 3 | -7.015252551 |
| 4 | 0.863691154 |

Examples
DCOTAN(x)
- x is the angle in radians.
| DCOTAN(Radian) | Value |
| SIN(0) | 0 |
| SIN(1) | 0.8414709848 |
| SIN(90) | 0.8939966636 |
