SEC(x)
- where x is the angle in Radians
- by default Calci use Radian as angle
DSEC can be used if the angle is in degrees.
The angle can be a single value or any complex array of values.
For example SEC(1..100) can give an array of the results, which is the COS value for each of the elements in the array. The array could be of any shape.
Description
Consider x = 90 then =SEC(RADIANS(90)) gives 0
The above function gives the Cosine of 'x' in Degree.
- In a right angled triangle, COS = Adjacent / Hypotenuse.
- By default, Calci takes the angle in Radians.
- To convert Radian to Degree multiply with 180/PI() or we have to use the Radians function SEC(RADIAN(x))or DSEC(x).
- SSEC function determines the Cosine of the given angle.
The following example shows how SEC is applied to an array of numbers containing numbers 1..10.
1..10@SEC
| Number | SEC |
|---|---|
| 1 | 0.54030230586 |
| 2 | -0.41614683654 |
| 3 | -0.9899924966 |
| 4 | -0.65364362086 |
| 5 | 0.28366218546 |
| 6 | 0.96017028665 |
| 7 | 0.75390225434 |
| 8 | -0.1455000338 |
| 9 | -0.91113026188 |
| 10 | -0.83907152907 |
Examples
SEC(x)
- x is the angle in radians.
| SEC(Radian) | Value |
| COS(0) | 0 |
| SEC(1) | 0.54030230586 |
| SEC(90) | -0.44807361612 |
