Q. A hyperbola centered at the origin has vertices at (0,±6) (0, \pm \sqrt{6}) and foci at (0,±74) (0, \pm \sqrt{74}) .\newlineWrite the equation of this hyperbola.
  1. Standard Form of Hyperbola Equation: Identify the standard form of the equation for a hyperbola with a vertical transverse axis.\newlineStandard form of equation for a hyperbola with a vertical transverse axis: \newline(yk)2/a2(xh)2/b2=1(y-k)^2/a^2 - (x-h)^2/b^2 = 1
  2. Determining the Center: Determine the center (h,k)(h, k) of the hyperbola. Since the hyperbola is centered at the origin, h=0h = 0 and k=0k = 0.
  3. Finding the Semi-Major Axis: Find the value of the semi-major axis aa. The vertices are at (0,±6)(0, \pm\sqrt{6}), so a=6a = \sqrt{6}.
  4. Calculating the Distance to the Foci: Calculate the distance cc between the center and the foci. The foci are at (0,±74)(0, \pm\sqrt{74}), so c=74c = \sqrt{74}.
  5. Using the Relationship between a, b, and c: Use the relationship c2=a2+b2c^2 = a^2 + b^2 to find the value of bb. Substitute the known values of aa and cc into the equation. c2=a2+b2c^2 = a^2 + b^2 742=62+b2\sqrt{74}^2 = \sqrt{6}^2 + b^2 74=6+b274 = 6 + b^2 b2=746b^2 = 74 - 6 b2=68b^2 = 68 b=68b = \sqrt{68}
  6. Writing the Equation in Standard Form: Write the equation of the hyperbola in standard form after substituting the values of hh, kk, aa, and bb. Substitute values of hh, kk, aa, and bb into (yk)2/a2(xh)2/b2=1(y-k)^2/a^2 - (x-h)^2/b^2 = 1. (y0)2/(6)2(x0)2/(68)2=1(y - 0)^2/(\sqrt{6})^2 - (x - 0)^2/(\sqrt{68})^2 = 1 kk00
