i could use some help understanding this question.
in the equation of the hyperbola x^2-y^2=9, e=_____
thanks for your help
DIVIDING BY 9
[X^2/3^2]-[Y^2/3^2]=1
STD.EQN. OF HYPERBOLA IS
[X^2/A^2]-[Y^2/B^2]=1
WHERE CENTER IS (0,0)
A=3......
B=3
ECCENTRICITY = E = SQRT[(A^2+B^2)/A^2]=SQRT[(3^2+3^2)/3^2]=SQRT(2)
