`asec`

Computes the principal inverse secant.

asec is evaluated through reciprocal/inverse-trigonometric identities when the input can be simplified; otherwise the expression remains symbolic.

Examples

These examples use Nerdamer Notation.

Evaluate an inverse secant when supported.

asec(2)

The same operation is available through the interfaces below.

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

asec(arg1)

Call the operation through the default nerdamer import.
