Equation of the hyperbola whose vertices are (± 3, 0) and foci at (± 5, 0), is
Given: Vertices are (±3, 0) and foci are (±5, 0)
To find: equation of the hyperbola
Formula used:
Standard form of the equation of hyperbola is,
Vertices of hyperbola are given by (±a, 0)
Foci of hyperbola are given by (±ae, 0)
Vertices are (±3, 0) and foci are (±5, 0)
Therefore,
a = 3 and ae = 5
⇒ 3 × e = 5
b2 = a2(e2 – 1)
⇒ b2 = 16
Equation of hyperbola:
⇒ 16x2 – 9y2 = 144
Hence, required equation of hyperbola is 16x2 – 9y2 = 144
