Answer

\(\boxed{\frac{y^2}{4} - \frac{x^2}{32} = 1}\) is the standard form of the equation of the hyperbola.

Steps

Step 1 :The standard form of the equation of a hyperbola with its center at the origin (0,0) is given by: \[\frac{x^2}{a^2} - \frac{y^2}{b^2} = 1\] if the transverse axis is along the x-axis, and \[\frac{y^2}{a^2} - \frac{x^2}{b^2} = 1\] if the transverse axis is along the y-axis.

Step 2 :In this case, since the foci and vertices are along the y-axis, the transverse axis is along the y-axis. Therefore, the equation of the hyperbola is of the form: \[\frac{y^2}{a^2} - \frac{x^2}{b^2} = 1\]

Step 3 :The distance from the center to a focus is c, and the distance from the center to a vertex is a. Therefore, we have: \[c = 6\] and \[a = 2\]

Step 4 :We also know that for a hyperbola, \[c^2 = a^2 + b^2\]. We can use this equation to solve for b.

Step 5 :Substituting the values of a and c into the equation, we get \[b = \sqrt{c^2 - a^2} = \sqrt{6^2 - 2^2} = \sqrt{32} = 5.656854249492381\]

Step 6 :Substituting the values of a and b into the equation of the hyperbola, we get \[\frac{y^2}{4} - \frac{x^2}{32} = 1\]

Step 7 :\(\boxed{\frac{y^2}{4} - \frac{x^2}{32} = 1}\) is the standard form of the equation of the hyperbola.
