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
