DCOS(x)


  • where x is the angle in Radians
  • by default Calci use Radian as angle

COS can be used if the angle is in Radians.

Description

  • This function is used to obtain the COS value of 'x' in Degrees.
  • It is the reciprocal of SEC function i.e,COS(x) = 1 / SEC(x).
  • In a right angled triangle COS(x) = Adjacent side / Hypotenuse.
  • 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 angle can be a single value or any complex array of values.

The following example shows how DSEC is applied to an array of numbers containing numbers 1..10.

  • Type =1..10@DCOS in Calci
  • Type =1..10@DCOS or 1..10@DCOS in ZOS
Number DCOS
1 0.999847695
2 0.999390827
3 0.998629535
4 0.99756405
5 0.996194698
6 0.994521895
7 0.992546152
8 0.990268069
9 0.987688341
10 0.984807753

Examples

DCOS(x)

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