Given, in a hyperbola

 Vertices (0, ± 3), foci (0, ± 5)

Here, Vertices and focii are on the Y-axis so, the standard equation of the Hyperbola will be ;

\frac{y^2}{a^2}-\frac{x^2}{b^2}=1

By comparing the standard parameter (Vertices and foci) with the given one, we get

a=3 and c=5

Now, As we know the relation  in a hyperbola 

c^2=a^2+b^2

b^2=c^2-a^2

b^2=5^2-3^2

b^2=25-9=16

Hence, The Equation of the hyperbola is ;

\frac{y^2}{9}-\frac{x^2}{16}=1.
