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@DTAN in Calci
- Type =1..10@DTAN or 1..10@DTAN in ZOS
| Number | DTAN |
|---|---|
| 1 | 0.017455065 |
| 2 | 0.034920769 |
| 3 | 0.052407779 |
| 4 | 0.069926812 |
| 5 | 0.087488664 |
| 6 | 0.105104235 |
| 7 | 0.122784561 |
| 8 | 0.140540835 |
| 9 | 0.15838444 |
| 10 | 0.176326981 |
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 |
