So I have this equation: 36x^2-121y^2=49
Which I rearranged to 36x^2/49-121y^2/49=1
So I want to go from here and find the eccentricity,foci,asymptotes etc...
But I'm getting myself confused. Since my equation is of the form x^2/a^2-y^2/b^2=1
Both a and b would be 7^2... which makes my eccentricity e=sqrt(1+49/49) but this is at odds with the software I'm using to practice this.
Which part am I getting myself tied up with?
Thank you!
