Am o nedumerire la formula parabolei cu axa de simetrie OY:
aici formula parabolei este x^2=4yp (este si o demonstratie), iar in unele carti am gasit formula aceleiasi parabole ca fiind x^2=2yp. Care este corecta?

Gandeste-te si tu, care poate fi corecta? Conteaza? \( p \) este un numar real ..., si daca vreau pot sa scriu si \( x^2=100yp \)...

Tomorow is a mistery,

That's why it's called present.
