FAQs on JEE Main Previous Year Questions (2025): Hyperbola

1. What is the standard form of a hyperbola?
Ans. The standard form of a hyperbola is given by the equations (x²/a²) - (y²/b²) = 1 for a hyperbola that opens horizontally, and (y²/a²) - (x²/b²) = 1 for a hyperbola that opens vertically. Here, 'a' and 'b' are constants that determine the shape and size of the hyperbola.
2. How do you find the foci of a hyperbola?
Ans. The foci of a hyperbola are found using the relationship c² = a² + b², where 'c' is the distance from the center to each focus, 'a' is the distance from the center to a vertex, and 'b' is related to the distance to the co-vertices. For a hyperbola centered at the origin with a horizontal transverse axis, the foci are located at (±c, 0), and for a vertical transverse axis, they are at (0, ±c).
3. What is the eccentricity of a hyperbola and how is it calculated?
Ans. The eccentricity (e) of a hyperbola is a measure of how "stretched" the hyperbola is, and it is calculated using the formula e = c/a, where 'c' is the distance from the center to a focus, and 'a' is the distance from the center to a vertex. The eccentricity of a hyperbola is always greater than 1.
4. Can you explain the asymptotes of a hyperbola?
Ans. The asymptotes of a hyperbola are straight lines that the hyperbola approaches but never touches. For a hyperbola in standard form (x²/a²) - (y²/b²) = 1, the equations of the asymptotes are y = (b/a)x and y = -(b/a)x. For (y²/a²) - (x²/b²) = 1, the asymptotes are y = (a/b)x and y = -(a/b)x.
5. How do transformations affect the graph of a hyperbola?
Ans. Transformations such as translations, reflections, and dilations can affect the graph of a hyperbola. A translation shifts the hyperbola's center to a new point (h, k), changing the standard form to (x-h)²/a² - (y-k)²/b² = 1 for horizontal hyperbolas and (y-k)²/a² - (x-h)²/b² = 1 for vertical ones. Reflections can flip the hyperbola across an axis, while dilations change the distance of the vertices and foci from the center, altering its overall shape.
