DTAN(Number)
- Number is the angle in Degrees.
- DTAN(),returns the double-precision tangent of given angle.
TAN can be used if the angle is in Radians.
The angle can be a single value or any complex array of values.
For example DTAN(1..100) can give an array of the results, which is the TAN value for each of the elements in the array. The array could be of any values either '+' or '-' like 1..5@DTAN or (-5)..(-1)@DTAN.
Description
- In a right angled triangle, TAN = Opposite side / Adjacent side or SIN / COS.
- This function is used to obtain the Tangent value of 'x' in Degrees.
- 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 following example shows how DTAN is applied to an array of numbers containing angles 1..10.
- Type =1..10@DTAN in Calci
- Type =1..10@DTAN or 1..10@DTAN in ZOS
| Angles | 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 degrees.
- TAN(-x)=-TAN(x)
- Result shows TAN(abc)= NAN
| DTAN(degrees) | Value |
| DTAN (0) | 0 |
| DTAN (1) | 0.017455065 |
| DTAN (-45) | -1 |
