Calculate Inverse tangent of a value in R Programming – atan() Function

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

Syntax: atan(x)

Parameter:
x: Numeric value

Example 1:

# R code to calculate inverse tangent of a value

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

# Using atan() Function
atan(x1)
atan(x2)

Output:

[1] -0.7853982
[1] 0.4636476

Example 2:

# R code to calculate inverse tangent of a value

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

# Using atan() Function
atan(x1)
atan(x2)

Output:

[1] 0.2209213
[1] 0.4284381
