DCOSEC(x)
- where x is the angle in Radians
- by default Calci use Radian as angle
COSEC can be used if the angle is in Radians.
Description
- This function is used to obtain the Cosecant value of 'x' in degrees.
- It is the reciprocal of SIN function i.e, COSEC(x) = 1 / SIN(x).
- In a right angled triangle COSEC(x) = Hypotenuse / Opposite side.
- To obtain the value in Radians multiply with PI()/180 or use COSEC function COSEC(X)
- DCOSEC 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 COTAN is applied to an array of numbers containing numbers 1..10.
- Type =1..10@DSEC in Calci
- Type =1..10@DSEC or 1..10@DSEC in ZOS
| Number | DSEC |
|---|---|
| 1 | 1.000152328 |
| 2 | 1.000609544 |
| 3 | 1.001372346 |
| 4 | 1.002441898 |
| 5 | 1.003819838 |
| 6 | 1.00550828 |
| 7 | 1.007509825 |
| 8 | 1.009827573 |
| 9 | 1.012465126 |
| 10 | 1.015426612 |
Examples
DSEC(x)
- x is the angle in radians.
- SEC(-X)=-SEC(X)
- Result shows COTAN(abc)= NAN
| DSEC(Radian) | Value |
