COS(x)


  • where x 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

This fuction gives the cosine of 'x'. In a right angled triangle,COS=adjacent/hypotenuse. It will give the value in radians.To convert that in degrees multiply with PI()/180 or we have to use the radians function.

  • 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(x)

  • x   is the angle in radians.
COS(Radian) Value
COS(0) 0
COS(1) 0.54030230586
COS(90) -0.44807361612
