CE ÎNSEAMNĂ HYPERBOLOID ÎN ENGLEZĂ?
hiperboloid
În matematică, un hiperboloid este un tip quadric - un tip de suprafață în trei dimensiuni - descris de ecuație, sau. Ambele suprafete asimptoteaza la aceeasi suprafata conica ca si x sau y devin mari: Acestea sunt de asemenea numite hiperboloide eliptice. Dacă și numai dacă a = b, acesta este un hiperboloid de revoluție, și este, de asemenea, numit hiperboloid circular ....
Definiția hyperboloid în dicționarul Engleză
Definiția hiperboloidului din dicționar este o suprafață geometrică formată dintr-o singură coală sau din două foi separate printr-o distanță finită, ale cărei secțiuni paralele cu cele trei planuri de coordonate sunt hiperbola sau elipse. Ecuațiile x² / a² + y² / b² - z² / c² = 1 sau x² / a² - y² / b² - z² / c² = 1 unde a, b și c sunt constante.

Suppose we start with the disk radiator and we place a mirror in the form of a
hyperboloid of revolution coincident with a set of flow lines as in Figure 6.10. We
truncate the mirror at some distance so the open end is a circle of diameter AA¢.
