Find the formula of finding the vertices of fundamental rectangle and the equations of asymptotes. Explain how did it happen.Please Find how to get the vertices of fundamental rectangle and equations of asymptotes.

Given this example:

x²/9 - y²/25 = 1

Answer:

Vertices (-1,0) , (1,0)

Vertices of the fundamental rectangle (1,5), (-1,5),(-1,-5)

Equations of Asymptotes ; 5x + y = 0 , 5x - y = 0
