Calculate arc cosine of a value in R programming - acos() function

Calculate Inverse cosine of a value in R Programming - acos() Function

Last Updated : 01 Jun, 2020

acos() function in R Language is used to calculate the inverse cosine value of the numeric value passed to it as argument.

Syntax: acos(x) Parameter: x: Numeric value

Example 1:

Python3 1==

# R code to calculate inverse cosine of a value

# Assigning values to variables 
x1 <- -1
x2 <- 0.5

# Using acos() Function
acos(x1)
acos(x2)

Output:

[1] 3.141593
[1] 1.047198

Example 2:

Python3 1==

# R code to calculate inverse cosine of a value

# Assigning values to variables
x1 <- 0.224587
x2 <- 0.456732

# Using acos() Function
acos(x1)
acos(x2)

Output:

[1] 1.344277
[1] 1.096478
