`atan`

Computes the principal arctangent in radians.

Known inputs are reduced to exact multiples of pi when possible. Positive and negative infinity map to plus or minus pi/2.

Examples

These examples use Nerdamer Notation.

Use an exact inverse-trig value.

atan(1)
// → (1/4)*pi

Keep a symbolic arctangent.

atan(x)

The same operation is available through the interfaces below.

Use this form inside input passed to nerdamer(...).

atan(arg1)

Call the operation through the default nerdamer import.
