Syntax

math.atan(x)
  • x: The number representing the tangent.

Example

In this example, math.atan() calculates the arctangent of 1.

local x = 1
local answer = math.atan(x)


local output = string.format("The arctangent of %.2f is approximately %.4f", x, answer)
print(output)

This will result in the following output below.

The arctangent of 1.00 is approximately 0.7854
