Find the equation of the hyperbola whose vertices are (±2, 0) and the eccentricity is 2.
Given: Vertices are (±2, 0) and the eccentricity is 2
Need to find: The equation of the hyperbola.
Let, the equation of the hyperbola be:
Vertices are (±2, 0), that means, a = 2
And also given, the eccentricity, e = 2
A and B are the foci.
We know that,
Therefore,
⇒
⇒ [Squaring both sides]
⇒
⇒ [As a = 2]
So, the equation of the hyperbola is,
⇒
