THIS MIGHT HELP :)

Answer 2

Thanks, Do you know whether fact that there is a scalar coeffecient before y when you simplify it down to -1 = x^2 - (9y^2)/4
Mean you have to do anything special or do you just calculate asymptotes as usual?

Answer 3

uhm. i really don't know. SORRY , maybe ask again for other's help. :)
