Standard Form of a Vertical Hyperbola with Center (0,0)(0, 0)

For a hyperbola centered at the origin, (0,0)(0, 0), if the y2y^2-term is positive, its transverse axis lies on the yy-axis and its branches open up and down. The standard form of this equation is y2a2x2b2=1\frac{y^2}{a^2} - \frac{x^2}{b^2} = 1. The hyperbola has vertices and yy-intercepts at (0,a)(0, -a) and (0,a)(0, a), and it has no xx-intercepts.
