COS(n)
- where n is in Radians
- by default Calci use Radian as angle
DCOS can be used if the angle is in degrees.
The angle can be a single value or any complex array of values.
For example COS(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 n = 90 then =COS(RADIANS(90)) gives 1
- COS function determines the sine of the given angle.
The following example shows how COS is applied to an array of numbers containing numbers 1..10.
1..10@COS
| Number | COS |
|---|---|
| 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
COS(n)
- n is the angle in radians.
| COS(Radian) | Value |
| COS(0) | 0 |
| COS(1) | 0.54030230586 |
| COS(90) | -0.44807361612 |
