DCOS(x)


  • where x 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)
  • DSEC returns NaN if 'x' is not real

The following example shows how DSEC 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
Angles DCOS
1 0.999847695
2 0.999390827
3 0.998629535
4 0.99756405
5 0.996194698
6 0.994521895

8 0.990268069
9 0.987688341
10 0.984807753

Examples

DCOS(x)

  • x   is the angle in degrees.
  • COS(-x)=COS(x)
  • Result shows DCOS(abc)= NAN
DCOS(Degrees) Value
DSEC(0) 1
DCOS(1) 0.999847695
DCOS(90) 0
