The in

`arc tangent`

function`R`

returns the Figure 1 below shows the mathematical representation of the `atan()`

function.

Figure 2 shows the visual representation of the `atan()`

function.

To convert `radians`

to `degrees`

, use:

```
degrees = radians * ( 180.0 / pi )
```

```
atan(num)
```

This function requires a number as a parameter.

`atan()`

will return the inverse tangent of a number (radians) sent as a parameter. The return values lie in the interval `[-pi/2,pi/2]`

in radians.

#Positive number in radians a <- atan(0.5); print(paste0("atan(0.5): ", a, " radians")) #negative number in radians b <- atan(-0.5); print(paste0("atan(-0.5): ", b, " radians")) #applying atan() and then converting the result in radians to degrees #radians = 1.0 c <- atan(1) * (180.0 / pi); print(paste0("tan(1): ", c, " degrees"))
