WebThe main bulk of her work on Cremona transformations, however, was notable for the reason that the methods she employed were basically elementary—largely analytical geometry—but her success in their use was the result of a powerful, almost uncanny, geometrical intuition which enable her to extract correct answers in her own way to quite …
