If the hyperbola and ellipse 3x ^ 2 + 4Y ^ 2 = 48 are in common focus, and the real axis length is equal to 2, then the hyperbolic equation is?

If the hyperbola and ellipse 3x ^ 2 + 4Y ^ 2 = 48 are in common focus, and the real axis length is equal to 2, then the hyperbolic equation is?

C of hyperbola is the same as that of ellipse, which is 2
The real axis length is equal to 2, that is, a = 1
∴b^2=3
The focus of hyperbola and ellipse are the same, they are on the X axis
The equation is x ^ 2-y ^ 2 / 3 = 1
