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

Syntax: cos(x)

Parameter:
x: Numeric value

Example 1:

# R code to calculate cosine of a value 
  
# Assigning values to variables 
x1 <- 90
x2 <- 30
  
# Using cos() Function 
cos(x1) 
cos(x2) 

Output:

[1] -0.4480736
[1] 0.1542514

Example 2:

# R code to calculate cosine of a value 
  
# Assigning values to variables 
x1 <- pi 
x2 <- pi / 3
  
# Using cos() Function 
cos(x1) 
cos(x2) 

Output:

[1] -1
[1] 0.5
