Q. A hyperbola centered at the origin has vertices at (±33,0) and foci at (±59,0).Write the equation of this hyperbola.
Identify Hyperbola Equation: The equation of a hyperbola centered at the origin with horizontal transverse axis is given by (a2x2)−(b2y2)=1, where 2a is the distance between the vertices and 2c is the distance between the foci. We are given the vertices at (±33,0), so a=33.
Find Distance Between Vertices and Foci: Next, we are given the foci at (±59,0), so c=59. The relationship between a, b, and c in a hyperbola is c2=a2+b2. We can use this to solve for b2.
Calculate b2: Substitute the known values of a and c into the relationship c2=a2+b2 to find b2.(59)2=(33)2+b259=33+b2b2=59−33b2=26
Write Hyperbola Equation: Now that we have a2 and b2, we can write the equation of the hyperbola. Substitute a2=33 and b2=26 into the standard equation of the hyperbola.(33x2)−(26y2)=1
