Identify the standard form of the hyperbola equation. The given equation is \( \frac{y^2}{4} - x^2 = 1 \), which is in the form \( \frac{y^2}{a^2} - \frac{x^2}{b^2} = 1 \). This indicates a vertical hyperbola.
Determine the values of \( a^2 \) and \( b^2 \). From the equation, \( a^2 = 4 \) and \( b^2 = 1 \). Therefore, \( a = 2 \) and \( b = 1 \).
Find the vertices of the hyperbola. For a vertical hyperbola, the vertices are located at \( (0, \pm a) \). Thus, the vertices are \( (0, 2) \) and \( (0, -2) \).
Calculate the distance to the foci using the formula \( c^2 = a^2 + b^2 \). Substitute the known values: \( c^2 = 4 + 1 = 5 \), so \( c = \sqrt{5} \).
Determine the coordinates of the foci. For a vertical hyperbola, the foci are at \( (0, \pm c) \). Therefore, the foci are \( (0, \sqrt{5}) \) and \( (0, -\sqrt{5}) \).
