Calculate cosine of a value in R Programming – cos() Function

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
