Calculate arc cosine of a value in R programming - acos() function Last Updated : 10 May, 2020 Comments Improve Suggest changes Like Article Like Report The acos() is an inbuilt function in R Programming which is used to calculate arc cosine of the specified radian value and output is also in radians. Syntax: acos(radian) Return: Returns the arc cosine value of radian. Example 1: Python3 # Using acos() method gfg <- acos(pi/4) print(gfg) Output: [1] 0.7853982 Example 2: Python3 # Using acos() method gfg <- acos(pi/6) print(gfg) Output: [1] 1.019727 Comment More infoAdvertise with us Next Article Calculate arc cosine of a value in R programming - acos() function J jitender_1998 Follow Improve Article Tags : R Language Similar Reads Calculate Inverse cosine of a value in R Programming - acos() Function acos() function in R Language is used to calculate the inverse cosine value of the numeric value passed to it as argument.
