DCOS(Number)
- is the angle in Degree.
is the angle in Degree. COS can be used if the angle is in Radians.
The angle can be a single value or any complex array of values.
For example DCOS(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 values either '+' or '-' like 1..5@DCOS or (-5)..(-1)@DCOS.
Description
- In a right angled triangle, COS = Adjacent side / Hypotenuse.
- This function is used to obtain the COS value of 'x' in Degrees.
- To obtain the value in Radians multiply with PI()/180 or use COS function COS(x)
- DCOS returns NaN if 'x' is not real
The following example shows how DCOS is applied to an array of numbers containing angles 1..10.
- Type =1..10@DCOS in Calci
- Type =1..10@DCOS or 1..10@DCOS in ZOS

Examples
DCOS(Number)
- Number is the angle in degrees.
- COS(-x)=COS(x),Here x is any Number.
- Result shows DCOS(abc)= NAN
| DCOS(Degrees) | Value |
