The standard form of a hyperbola with a vertical transverse axis is $\frac{y^2}{a^2} - \frac{x^2}{b^2} = 1$, where $2a$ is the distance between the vertices and $c$ is the distance from the center to a focus. Given vertices at (0, ±5), $a = 5$, so $a^2 = 25$. Given foci at (0, ±6), $c = 6$, so $c^2 = 36$. Using $c^2 = a^2 + b^2$, we find $b^2 = c^2 - a^2 = 36 - 25 = 11$. Thus, the equation is $\frac{y^2}{25} - \frac{x^2}{11} = 1$.
