Final Answer: The equation of the hyperbola is y24x212=1.

Steps

Step 1 :The standard form of the equation of a hyperbola with its center at the origin (0,0) is given by x2a2y2b2=1 if the transverse axis is along the x-axis, and y2a2x2b2=1 if the transverse axis is along the y-axis.

Step 2 :In this case, the foci and vertices are along the y-axis, so the transverse axis is along the y-axis. The distance from the center to a focus is c, and the distance from the center to a vertex is a.

Step 3 :Given that the foci are at (0,-4) and (0,4), the distance from the center to a focus is c=4.

Step 4 :Given that the vertices are at (0,2) and (0,-2), the distance from the center to a vertex is a=2.

Step 5 :We can find b using the relationship c2=a2+b2.

Step 6 :Let's calculate b2 using this relationship. a=2,c=4, so b2=c2a2=12.

Step 7 :The value of b2 is 12. Now we can write the standard form of the equation of the hyperbola. Since the transverse axis is along the y-axis, the equation is y2a2x2b2=1.

Step 8 :Final Answer: The equation of the hyperbola is y24x212=1.
