Q. A hyperbola centered at the origin has vertices at (0,±12) and foci at (0,±45).Write the equation of this hyperbola.
Standard Form of Hyperbola Equation: Identify the standard form of the equation for a hyperbola centered at the origin with a vertical transverse axis.Standard form of equation for a hyperbola with vertical transverse axis: (y−k)2/a2−(x−h)2/b2=1 where (h,k) is the center of the hyperbola.
Determining the Center: Determine the center (h,k) of the hyperbola. Since the hyperbola is centered at the origin, we have h=0 and k=0.
Finding the Semi-Major Axis: Find the value of the semi-major axis a. The vertices are given at (0,±12), so the distance from the center to a vertex is 12. Therefore, a=12.
Finding the Semi-Minor Axis: Find the value of the semi-minor axis b using the relationship c2=a2+b2, where c is the distance from the center to a focus.The foci are given at (0,±45), so c=45. We already know that a=12. We can now solve for b.c2=a2+b2(45)2=(12)2+b245=12+b2c2=a2+b20c2=a2+b21c2=a2+b22
Writing the Equation in Standard Form: Write the equation of the hyperbola in standard form after substituting the values of h, k, a, and b. Substitute h=0, k=0, a=12, and b=33 into the standard form equation (y−k)2/a2−(x−h)2/b2=1. (y−0)2/(12)2−(x−0)2/(33)2=1k0
