Functiones trigonometricae inversae

Functiones trigonometricae inversae sunt functiones inversae functionum trigonometricarum, quibus angulus ex rationibus trigonometricis anguli computantur. praefixo arc aut numero superiori −1 notantur. Secunda autem notatio potest ad ambiguitatem ducere, quia sin−1, exempli gratia, intellegi potest ut , hoc est csc A (cosecans).
