a' (a prima)

[Marco PCA]

Hola,

¿Cómo se dice en inglés "A prima" cuando uno se refiere en matemáticas a la A que tiene el apóstrofo (A')?

Gracias,
Marco

A′ ---> A prime ---> /eɪ/ /praɪm/

('A' se dice 'éhi' )
('prime' se dice 'praim')


The prime symbol ( ′ ), double prime symbol ( ″ ), triple prime symbol ( ‴ ), quadruple prime symbol ( ⁗ ) etc., are used to designate units and for other purposes in mathematics, the sciences, linguistics and music.

Double and triple prime? Funny, we say 'prima, segunda, tercera...'
"f de x es seno de x, f prima de x es coseno de x, f segunda de x es menos seno de x..."

We can also say 'first derivative', 'second derivative', etc.

Yes, but since prima, segunda, ... are widely used for the derivatives in written equations, when you are reading aloud you see f', f'' and f''' and say it like that: f prima, f segunda, f tercera.
If I were teaching kids how to do derivatives then I would write f'' and say 'la derivada segunda de f', using better language.

Okay. Then it is different in English! We say, 'prime', 'double prime', etc.
