“COS”
Used for – “COS” is used find the value of cosine of the angle which is written in radians in MS excel and display the end
result achieved.
Syntax – COS(Angle).
Example – Let us continue with the
example of Degree, we have a value in cell B1 0.523599 which comes as result of
formula Radian & value in cell C1 30 which comes as result of formula Degree
and wants excel tells the value of cos of these angles then you can write up the formula as =COS(B1) in cell B2 and Excel
came with answer 0.866025 which is the value equal to cos of angle 0.523599 Radian.

You
can check it yourself by copy the highlighted table and pasting in the first
cell of the spread sheet.
NOTE:
Here you must note that this formula only reads value in radians as per
default. So please always converts degree angle to radian angle before using
this formula. See the variation you get if you did not convert value into radians
first.
